Mushaf View — Surah 2 2:157

The Believer is Patient with the Affliction and thus gains a Reward
Allah informs us that He tests and tries His servants, just as He said in another Ayah:
وَلَنَبْلُوَنَّكُمْ حَتَّى نَعْلَمَ الْمُجَـهِدِينَ مِنكُمْ وَالصَّـبِرِينَ وَنَبْلُوَ أَخْبَـرَكُمْ
(And surely, We shall try you till We test those who strive hard (for the cause of Allah) and As-Sabirin (the patient), and We shall test your facts (i.e., the one who is a liar, and the one who is truthful).) (47:31)
Hence, He tests them with the bounty sometimes and sometimes with the afflictions of fear and hunger. Allah said in another Ayah:
فَأَذَاقَهَا اللَّهُ لِبَاسَ الْجُوعِ وَالْخَوْفِ
(So Allah made it taste extreme of hunger (famine) and fear.) (16:112)
The frightened and the hungry persons show the effects of the affliction outwardly and this is why Allah has used here the word `Libas' (cover or clothes) of fear and hunger. In the Ayat above, Allah used the words:
بِشَيْءٍ مِّنَ الْخَوفْ وَالْجُوعِ
(with something of fear, hunger,) meaning, a little of each. Then (Allah said),
وَنَقْصٍ مِّنَ الاٌّمَوَالِ
(loss of wealth,) meaning, some of the wealth will be destroyed,
وَالاٌّنفُسِ
(lives) meaning, losing friends, relatives and loved ones to death,
وَالثَّمَرَتِ
(and fruits,) meaning, the gardens and the farms will not produce the usual or expected amounts. This is why Allah said next:
وَبَشِّرِ الصَّـبِرِينَ
(but give glad tidings to As-Sabirin (the patient).)
He then explained whom He meant by `the patient' whom He praised:
الَّذِينَ إِذَآ أَصَـبَتْهُم مُّصِيبَةٌ قَالُواْ إِنَّا لِلَّهِ وَإِنَّـآ إِلَيْهِ رَجِعونَ
(Who, when afflicted with calamity, say: "Truly, to Allah we belong and truly, to Him we shall return.") meaning, those who recite this statement to comfort themselves in the face of their loss, know that they belong to Allah and that He does what He wills with His servants. They also know that nothing and no deed, even if it was the weight of an atom, will be lost with Allah on the Day of Resurrection. These facts thus compel them to admit that they are Allah's servants and that their return will be to Him in the Hereafter.
This is why Allah said: t
أُولَـئِكَ عَلَيْهِمْ صَلَوَتٌ مِّن رَّبْهِمْ وَرَحْمَةٌ
(They are those on whom are the Salawat (i. e., who are blessed and will be forgiven) from their Lord, and (they are those who) receive His mercy,) meaning, Allah's praise and mercy will be with them. Sa`id bin Jubayr added, "Meaning, safety from the torment."
وَأُولَـئِكَ هُمُ الْمُهْتَدُونَ
(and it is they who are the guided ones.) `Umar bin Al-Khattab commented: "What righteous things, and what a great heights.
أُولَـئِكَ عَلَيْهِمْ صَلَوَتٌ مِّن رَّبْهِمْ وَرَحْمَةٌ
(They are those on whom are the Salawat from their Lord, and (they are those who) receive His mercy) are the two righteous things.
وَأُولَـئِكَ هُمُ الْمُهْتَدُونَ
(and it is they who are the guided ones) are the heights."
The heights means more rewards, and these people will be awarded their rewards and more.
The Virtue of asserting that We all belong to Allah, during Afflictions
There are several Ahadith that mention the rewards of admitting that the return is to Allah by saying:
إِنَّا لِلَّهِ وَإِنَّـآ إِلَيْهِ رَجِعونَ
("Truly, to Allah we belong and truly, to Him we shall return.") when afflictions strike. For instance, Imam Ahmad reported that Umm Salamah narrated: Once, Abu Salamah came back after he was with Allah's Messenger ﷺ and said: I heard Allah's Messenger ﷺ recite a statement that made me delighted. He said:
«لَا يُصِيبُ أَحَدًا مِنَ الْمُسْلِمِينَ مُصِيبَةٌ فَيَسْتَرْجِعُ عِنْدَ مُصِيبَتِهِ ثُمَّ يقُولُ: اللَّهُمَّ أْجُرْنِي فِي مُصِيبَتِي وأَخْلِفْ لِي خَيْرًا مِنْهَا، إِلَّا فَعَلَ ذلِكَ بِه»
(No Muslim is struck with an affliction and then says Istirja` when the affliction strikes, and then says: `O Allah! Reward me for my loss and give me what is better than it,' but Allah will do just that.) Umm Salamah said: So I memorized these words. When Abu Salamah died I said Istirja` and said: "O Allah! Compensate me for my loss and give me what is better than it." I then thought about it and said, "Who is better than Abu Salamah" When my `Iddah (the period of time before the widow or divorced woman can remarry) finished, Allah's Messenger ﷺ asked for permission to see me while I was dyeing a skin that I had. I washed my hands, gave him permission to enter and handed him a pillow, and he sat on it. He then asked me for marriage and when he finished his speech, I said, "O Messenger of Allah ﷺ! It is not because I do not want you, but I am very jealous and I fear that you might experience some wrong mannerism from me for which Allah would punish me. I am old and have children." He said:
«أمَّا مَا ذَكَرْتِ مِنَ الْغَيْرَةِ فَسَوْفَ يُذْهِبُهَا اللهُ عَزَّ وَجَلَّ عَنْكِ، وَأَمَّا مَا ذَكَرْتِ مِنَ السِّنِّ فَقَدْ أَصَابَنِي مِثْلُ الَّذِي أَصَابَكِ، وَأَمَّا مَا ذَكَرْتِ مِنَ الْعِيَالِ فَإِنَّمَا عِيَالُكِ عِيَالِي»
(As for the jealousy that you mentioned, Allah the Exalted will remove it from you. As for your being old as you mentioned, I have suffered what you have suffered. And for your having children, they are my children too.) She said, "I have surrendered to Allah's Messenger ﷺ." Allah's Messenger ﷺ married her and Umm Salamah said later, "Allah compensated me with who is better than Abu Salamah: Allah's Messenger ﷺ." Muslim reported a shorter version of this Hadith.

(Such) those who have these traits (are they on whom are blessings) forgiveness (from their Lord) in this world, (and mercy) in that they are not tormented in the Hereafter. (And such are they who are rightly guided) to remember that we are Allah's and unto Him we shall return.

Upon those rest blessings forgiveness and mercy grace from their Lord and those — they are the truly guided to rectitude.

Patience in hardship: The way to make it easy
The nature and the significance of the severe test man is put to by Allah has been thoroughly discussed while explaining the verse’ وَإِذِ ابْتَلَىٰ إِبْرَ‌اهِيمَ رَ‌بُّهُ 'And when his Lord put Ibrahim to a test'.
Whatever their magnitude, accidents are unnerving. But a prior knowledge of such accidents makes it easier to bear them and be patient about them. Since the entire Ummah is addressed here, the Ummah should realize that the world is a place of hardships and labour; it is a place of ordeal. It will not, therefore, amount to impatience if one does regard such accidents as either strange or a remote chance. And as the Ummah, generally, displays the spirit of patience in all its deeds, the reward of Mercy is common to everyone who strives to be patient. But as the quality and degree of patience varies from person to person, everyone will be rewarded individually according to and commensurate with his quality of patience.
A formula of peace in hardship
That the patient people used to recite: إِنَّا لِلَّـهِ وَإِنَّا إِلَيْهِ رَ‌اجِعُونَ : 'We belong to Allah and to Him we are to return' is, in fact, an inculcation of the principle of virtue. The suggestion is that this is what the patient people should say as it brings excellent reward, relieves from the burden of sorrow and suffering and consoles effectively the grieved heart.

Prophet Abraham was a native of Iraq. Acting at God’s behest, he took his wife Hajar and his infant son Ishmael, and left them in the place now known as Makkah. There was no habitation there at that time and there was no water. Thirst forced Hajar to go far afield in search of water. Distressed, she ran back and forth between the hills of Safa and Marwah. After seven unsuccessful attempts, she returned to her dwelling. There she found a spring, now known as the spring of Zamzam, flowing from the ground. This was a symbolic event, showing us how Almighty God looks after His servants. If one persists in the service of God, finally reaching a stage where there is nothing but burning sand beneath one’s feet, then God in His mercy will cause a refreshing spring to gush forth from the dryness of the desert sands. When Muslims perform the pilgrimage to Makkah, they repeat Hajar’s historic quest between these hills, thus commemorating the profound relevance of the event to everyone who struggles in the path of God. God’s signs were displayed so clearly in the Prophet Muhammad’s life and teachings, that it was not difficult to see that he had been sent by God. Yet the Jewish intelligentsia denied him. They were prevented from believing in him by the fear that if they accepted an Arab prophet, their religious hegemony would come to an end. People would stop looking up to the Jews as their leaders. Old established religious traditions, and the interests, which had come to be associated with them, (the Jews being the main beneficiaries) would be destroyed. They deemed it wise to conceal the truth, for they thought that they would lose their worldly status were they to accept it; but it would have been much wiser for them to have proclaimed it. They forgot that God’s servants are required to put truth before their worldly interests. One who becomes destitute for the sake of the Lord gains succour from the inexhaustible treasures of divine grace. The doors of God’s mercy are always open to His servants. He will always forgive one who comes to his senses and mends his erring ways, proclaiming the truth as God wishes it to be proclaimed. Only those who persevere in their disbelief till the day they die will be deprived of His mercy.
