Qur'an
Surah 2 2:248
وَقَالَ لَهُمۡ نَبِیُّهُمۡ إِنَّ ءَایَةَ مُلۡكِهِۦۤ أَن یَأۡتِیَكُمُ ٱلتَّابُوتُ فِیهِ سَكِینَةࣱ مِّن رَّبِّكُمۡ وَبَقِیَّةࣱ مِّمَّا تَرَكَ ءَالُ مُوسَىٰ وَءَالُ هَـٰرُونَ تَحۡمِلُهُ ٱلۡمَلَـٰۤىِٕكَةُۚ إِنَّ فِی ذَ ٰلِكَ لَءَایَةࣰ لَّكُمۡ إِن كُنتُم مُّؤۡمِنِینَ ۝٢٤٨
Their prophet said to them, ‘The sign of his authority will be that the Ark [of the Covenant] will come to you. In it there will be [the gift of] tranquillity from your Lord and relics of the followers of Moses and Aaron, carried by the angels. There is a sign in this for you if you believe.’

Their Prophet then proclaimed, "The sign of the blessings of Talut's kingship over you is that Allah will give you back the Tabut (wooden box) that has been taken from you." Allah said:
فِيهِ سَكِينَةٌ مِّن رَّبِّكُمْ
(wherein is Sakinah from your Lord) meaning, peace (or grace) and reassurance. `Abdur-Razzaq stated that Qatadah said:
فِيهِ سَكِينَةٌ
(wherein is Sakinah) means grace. In addition, Ar-Rabi` said that Sakinah means mercy. This is also the meaning given by Ibn `Abbas, as Al-`Awfi narrated.
Allah then said:
وَبَقِيَّةٌ مِّمَّا تَرَكَ ءَالُ مُوسَى وَءَالُ هَـرُونَ
(...and a remnant of that which Musa (Moses) and Harun (Aaron) left behind,)
Ibn Jarir related that Ibn `Abbas said about this Ayah:
وَبَقِيَّةٌ مِّمَّا تَرَكَ ءَالُ مُوسَى وَءَالُ هَـرُونَ
(...and a remnant of that which Musa (Moses) and Harun (Aaron) left behind, ) Meaning, Moses' staff and the remnants of the Tablets. This is the same Tafsir of Qatadah, As-Suddi, Ar-Rabi` bin Anas and `Ikrimah, who added, "And also the Torah." `Abdur-Razzaq said that he asked Ath-Thawri about the meaning of,
وَبَقِيَّةٌ مِّمَّا تَرَكَ ءَالُ مُوسَى وَءَالُ هَـرُونَ
(...and a remnant of that which Musa (Moses) and Harun (Aaron) left behind,)
Ath-Thawri said, "Some said that it contained a pot of manna and the remnants of the Tablets, while some others said that it contained (Moses') staff and two shoes (and refer to 20:12)."
Allah then said:
تَحْمِلُهُ الْمَلَـئِكَةُ
(...carried by the angels.)
Ibn Jurayj stated that Ibn `Abbas said, "The angels came down while carrying the Tabut between the sky and the earth, until they placed it before Talut while the people were watching." As-Suddi said, "The Tabut was brought to Talut's house, so the people believed in the prophethood of Sham`un (Simeon) and obeyed Talut"
The Prophet then said:
إِنَّ فِي ذَلِكَ لأَيَةً لَّكُمْ
(Verily, in this is a sign for you) testifying to my truth in what I was sent with, my prophethood, and my command to you to obey Talut,
إِن كُنتُم مُّؤْمِنِينَ
(if you are indeed believers. ) in Allah and the Hereafter.

(And their Prophet) Samuel (said unto them: Lo! The token) the sign (of his kingdom) that it is from Allah (is that there shall come unto you the Ark) that was taken from you (wherein is peace of reassurance) mercy and tranquillity; it is also said that this means: it includes the wind (the triumph) of his victory, of golden colour in the form of a human face (from your Lord, and a remnant of that which the house of Moses) a remnant of Moses, i.e. his Scripture; as it is said: his tablets and staff (and the house of Aaron left behind) what Aaron had left behind, namely his cloak and turban, (the angels bearing it) the angels leading it. (Lo! Herein) in giving you back the Ark (shall be a token) a sign (for you) that he has been made king by Allah (if (in truth) ye are believers).

And their prophet said to them after they had demanded a sign of his kingship ‘The sign of his kingship is that there will come to you the Ark a chest containing the images of the prophets which God sent down to Adam and which was handed down to them sc. the Israelites until the Amalekites seized it from them in battle. They used to commence fighting invoking it before their enemy and marching behind it as well as experience peacefulness in its presence as God says therein is a Spirit of Peace reassurance for your hearts from your Lord and a remnant of what the folk of Moses and the folk of Aaron left behind which were Moses’s pair of sandals and his staff Aaron’s turban a measure qafīz of the manna that used to come down on them and the pieces of the broken tablets the angels bearing it tahmiluhu l-malā’ikatu the circumstantial qualifier referring to the subject of the verb ya’tiyakum ‘there will come to’. Surely in that shall be a sign for you of his kingship if you are believers’. The angels bore it between the earth and the sky while they gazed at it until finally they placed it before Saul. They then acknowledged his kingship and hastened to enlist in the holy struggle and he chose seventy thousand of their young men.

Commentary
1. Verse 246: إِذْ قَالُوا لِنَبِيٍّ لَّهُمُ ابْعَثْ لَنَا مَلِكًا نُّقَاتِلْ فِي سَبِيلِ اللَّـهِ (When they said to a prophet of theirs: "Send us a king so that we may fight in the way of Allah)."
These people from the Bani Isra'il had abandoned the injunctions given by Allah Almighty. When the infidel Amalekites were made to rule over them, they began thinking about correcting the situation. The name of the prophet mentioned here is Samuel (Arabic: Hebrew: Shemuel).
Verse 248: The story of Talut and Jalut
The Bani Isra'il used to have the legacy of a wooden chest (also identified as the Ark of the Covenant). Moses and other prophets of Bani Isra'il would keep this chest in the frontline of the battlefield. Its barakah بَرَکَہ (blessing, benediction) used to give them victory. When )Jalut: Goliath) overcame Bani Isra'il, he took this chest away with him. When Allah Almighty willed the return of the chest, it so happened that the infidels were struck by some epidemic or calamity at places where they carried this chest. Five cities were turned desolate. Nonplussed, they loaded it on two bullocks and drove them off. Then, the angels took control of the bullocks and made it reach Talut's doorsteps. (Talut is the Qur'anic name of the king known in the Bible as Saul) When the Bani Isra'il saw this sign, they believed in the kingdom of Talut, who then mounted an attack on Jalut while the weather was very hot.

The Israelites had a sacred chest, or box, known as the Ark of the Covenant (at-tabut), which they had had in their possession from the time they left Egypt. It contained the Ten Commandments engraved on stone, as well as relics of Moses and Aaron. This was a possession sacred to Israel. It served as a visible symbol of God’s gracious presence. It guided them on their journey, and led them on from victory to victory. It was lost to the enemy in the early part of Samuel’s ministry. But in the town where this Ark was placed, plague and pestilence broke out and the Philistines were terrified. Subsequently, they placed it on a driverless cart drawn by two cows. The beasts took it of their own accord to Bayt ash-Shamsh, a city of Judah. The Israelites were immensely overjoyed at its miraculous restoration.
