It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the people were performing the morning prayer in Quba when a man came and said: "The Qur'an has been revealed to the Messenger of Allah (peace and blessings be upon him) tonight, and he has been commanded to face the Ka'bah (in prayer)." They were praying towards Sham (the former qiblah), so they turned towards the Ka'bah during the prayer itself.

And with this same chain (it is narrated from Sayyiduna Ibn Umar, may Allah be pleased with them both) that the Messenger of Allah, peace and blessings be upon him, during travel, would perform (optional) prayers on his mount, facing whichever direction it was headed. Abdullah bin Dinar, may Allah have mercy on him, said: Abdullah bin Umar, may Allah be pleased with them both, would do the same.

It is narrated from Abu Salamah bin Abdur Rahman (may Allah have mercy on him) that when Sayyiduna Abu Hurairah (may Allah be pleased with him) led them in prayer, he would say the takbeer (Allahu Akbar) at every rising and lowering. Then when he finished the prayer, he would say: By Allah! I am the most similar among you to the prayer of the Messenger of Allah (peace and blessings of Allah be upon him).

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) began the prayer, he would raise his hands up to his shoulders, and when he bowed (for ruku‘), and when he raised his head from ruku‘, he would raise his hands in the same way and say:“ «سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ» ‏‏‏‏ Allah has heard the one who praises Him «رَبَّنَا وَلَكَ الْحَمْدُ» O our Lord! And all praise is for You.”And the Prophet (peace and blessings be upon him) would not raise his hands during prostrations (sujood).

And with the same chain of narration, it is narrated from Sayyiduna Sahl (bin Sa’d al-Sa’idi) رضي الله عنه that people were commanded that a man should place his right hand on his left forearm. Abu Hazim رحمه الله said: I know that he used to narrate it as marfu’.

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever performs a prayer in which Surah Al-Fatihah is not recited, that prayer is incomplete, incomplete, incomplete—it is not complete." (The narrator said) I said: O Abu Hurairah! Sometimes I am behind the Imam? So he (Sayyiduna Abu Hurairah, may Allah be pleased with him) shook my hand and then said: O Persian! Recite it in your heart, because I heard the Messenger of Allah (peace and blessings be upon him) say that Allah said: I have divided the prayer between Myself and My servant into two halves, so half is for Me and half is for My servant, and My servant will have what he asks for. The Messenger of Allah (peace and blessings be upon him) said: When the servant says «الْحَمْدُ لِلَّـهِ رَبِّ الْعَالَمِينَ» , Allah says: My servant has praised Me. When the servant says «الرَّحْمَـٰنِ الرَّحِيمِ» , Allah the Exalted says: My servant has extolled Me. When the servant says «مَالِكِ يَوْمِ الدِّينِ» , Allah the Exalted says: My servant has glorified Me. When the servant says: «‏‏‏‏إِيَّاكَ نَعْبُدُ وَإِيَّاكَ نَسْتَعِينُ» , then this is for the servant, and the servant will have what he asks for. When the servant says «اهْدِنَا الصِّرَاطَ الْمُسْتَقِيمَ . صِرَاطَ الَّذِينَ أَنْعَمْتَ عَلَيْهِمْ غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ» ‏‏‏‏, then this is for the servant, and the servant will have what he asks for." (The compiler of this book, Imam) Abu al-Hasan (al-Qabisi) said: Our narrators (of the Muwatta) have shown confusion in the wording of this hadith, so I have recorded the wording of (Abu al-Hasan Ali ibn Muhammad ibn Masrur) al-Dabbagh, except that this is according to the wording of Isa (ibn Miskin), and the copy was with al-Dabbagh, so this is the matter.

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) finished a prayer in which he had recited aloud, and he asked: "Has anyone among you just recited with me?" A man replied: "Yes, O Messenger of Allah! I have recited." So the Messenger of Allah (peace and blessings be upon him) said: "I say: Why is there contention (snatching) with me in the Qur'an?" (Az-Zuhri said): After hearing this, people stopped reciting (behind the Imam) in those prayers in which the Messenger of Allah (peace and blessings be upon him) would recite aloud.

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When the Imam says Ameen, you should also say Ameen, for whoever's Ameen coincides with the Ameen of the angels, his previous sins are forgiven." Ibn Shihab (az-Zuhri, may Allah have mercy on him) said: The Messenger of Allah (peace and blessings be upon him) used to say Ameen.

And with the same chain of narration, it is narrated from (Sayyiduna Abu Hurairah, may Allah be pleased with him) that the Messenger of Allah, peace and blessings be upon him, said: "When any one of you says Ameen, the angels in the heavens also say Ameen. Then if the Ameen of both coincides, the person's previous sins are forgiven."

And with the same chain of narration, it is narrated from (Sayyiduna Abu Huraira, may Allah be pleased with him) that the Messenger of Allah, peace and blessings be upon him, said: "When the Imam says «غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ» , then you should say Ameen, for whoever's saying coincides with the saying of the angels, his previous sins are forgiven."
