One day we were praying behind the Prophet. When he raised his head from bowing, he said, “Sami`a l-lahu liman hamidah.” A man behind him said, “Rabbana wa laka l-hamdu, hamdan kathiran taiyiban mubarakan fihi” (O our Lord! All the praises are for You, many good and blessed praises). When the Prophet completed the prayer, he asked, “Who has said these words?” The man replied, “I.” The Prophet said, “I saw over thirty angels competing to write it first.” Prophet rose (from bowing) and stood straight till all the vertebrae of his spinal column came to a natural position.
(who was one of the Badr warriors) Gabriel came to the Prophet (ﷺ) and said, “How do you look upon the warriors of Badr among yourselves?” The Prophet (ﷺ) said, “As the best of the Muslims.” or said a similar statement. On that, Gabriel said, “And so are the Angels who participated in the Badr (battle).
“When you hear the call, say what the Mu’adhdhin says.”
The Messenger of Allah (ﷺ) said: “When the Imam says: Not (the way) of those who earned Your anger, nor of those who went astray, say: ‘Amin,’ for if a person’s Amin coincides with the Amin of the angels, his previous sins will be forgiven.'”
When the Prophet (ﷺ) bowed, he said: “Allahumma laka rak’atu wa bika amantu wa laka aslamtu wa alayka tawwakaltu, anta Rabbi, khasha’a sam’i wa basri wa dammi wa lahmi wa ‘azmi wa ‘asabi Lillahi Rabbil-‘Alamin ( O Allah, to You I have bowed, in You I believe, to You I have submitted and in You I put my trust. You are my Lord. My hearing, my sight, my blood, my flesh, my bones and sinews are humbled before Allah, the Lord of the Worlds.)”
“When the Prophet (ﷺ) raised his head from bowing, he said: ‘Allahumma Rabbana wa lakal-hamd (O Allah, our Lord and to You be the praise).'”
“The Messenger of Allah (ﷺ) said when bowing and prostrating: ‘Subbuhun Quddusun Rabbul-mala’ikati war’ruh (Perfect, Most Holy, Lord of the Angels and the Spirit).”
“One day Allah’s Messenger was sitting in the Masjid” Rifa’ah said: “And we were with him. Then what appeared to be a Bedouin man entered to pray, but he performed his Salat in a very brief manner. He then got up and greeted the prophet with Salam. The Prophet said (returning the greeting): ‘And upon you. Go back and perform Salat, for indeed you have no prayed.’ So he returned to perform Salat then came and greeted the Prophet with Salam. So he (the Prophet) said (returning the greeting): ‘And upon you. Go back and perform Salat, for indeed you have not prayed.’ two or three times, each time coming to the Prophet, greeted the Prophet with Salam and the Prophet saying: ‘And upon you. Go back and perform Salat, for indeed you have not prayed.’ – until the people got scared and became very worried that one whose prayer was so brief had not actually prayed. Then in the end the man said: ‘Then show me, and teach me, for I am a human who has suffered and is mistaken.’ So he said: ‘Alright. When you stand for Salat then perform Wudu as Allah ordered you. Then say the Tashahhud, and the Iqamah as well. If you know any Quran then recite it, if not then praise Allah, mention His greatness, and the Tahlil. Then bow such that you are at rest in your bowing, then stand completely, then prostrate completely, then sit such that you are at rest while sitting them stand. When you have done that, then you have completed your Salat, and if you leave out something, then you have made your Salat deficient.’ And this was easier on them than the first matter, because if some of this was deficient, It would only reduce the reward of his Salat, it would not have gone entirely. “
The Prophet saw some sputum in the prayer direction of the mosque and he became so angry that his face turned red. Then a woman from among the Ansar came and scraped it off, and put some Khaluq on that spot. The Messenger of Allah said: “How good this is.”
