Sayyiduna Anas (may Allah be pleased with him) says: When {لَمْ یَکُنِ الَّذِیْنَ کَفَرُوْا} that is, Surah Bayyinah was revealed, the Messenger of Allah (peace and blessings be upon him) said to Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him): Allah Almighty has commanded me to recite this Surah {لَمْ یَکُنِ الَّذِیْنَ کَفَرُوْا} to you. He asked: Did Allah Almighty mention my name? The Prophet (peace and blessings be upon him) replied: Yes. Upon this, he began to weep.

Sayyiduna Abdullah bin Amr mentioned Sayyiduna Abdullah bin Mas’ud, may Allah be pleased with him, and then said: He is such a man whom I will always love, (the reason for this is that) I heard the Messenger of Allah, peace and blessings be upon him, say: Learn the Qur’an from four persons: the son of Umm ‘Abd, Mu’adh, and Salim, the freed slave of Abu Hudhayfah. So the Prophet, peace and blessings be upon him, mentioned him first. Ya’la, the narrator, says: I forgot the name of the fourth person.

(Second chain) It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) said: Learn the Qur’an from four persons: Abdullah bin Mas’ud, Salim the freed slave of Abu Hudhaifah, Mu’adh bin Jabal, and Ubayy bin Ka’b.

Wasi’ bin Hibban says: I said to Sayyiduna Abdullah bin Umar (may Allah be pleased with him): Tell me about the prayer of the Messenger of Allah (peace and blessings be upon him), how was it? He (in response) also mentioned this: Whenever he bowed his head and raised it, he would say the takbeer. Then he mentioned saying "As-salamu ‘alaykum wa rahmatullah" to the right side and "As-salamu ‘alaykum" to the left side.

Sayyiduna Anas bin Malik (may Allah be pleased with him) says: Sayyiduna Abu Bakr, Sayyiduna Umar, and Sayyiduna Uthman (may Allah be pleased with them) used to say Takbeer when they prostrated, when they stood up, and when they bowed.

Sayyiduna Abu Malik Ash'ari (may Allah be pleased with him) gathered his companions and said: Come, I will teach you the prayer of the Prophet of Allah. He was a man from the Ash'ari tribe. Then he asked for a tub, washed his hands three times, then rinsed his mouth and put water into his nose, and washed his face three times, then washed both arms three times, and after that wiped his head and ears, and then washed his feet. Then he led the Zuhr prayer, recited Surah Al-Fatihah in it, and said Allahu Akbar twenty-two times.

(Second chain of narration) In this it is stated: And he wiped over the apparent parts of his head and feet, then led them in prayer and said twenty-two takbirs. When he would prostrate and when he would raise his head from prostration, he would say Allahu Akbar. He recited Surah Al-Fatihah in both rak‘ahs and (by slightly raising his voice) made it audible to those near him.

It is narrated from Sayyiduna Abu Malik Ash'ari (may Allah be pleased with him) that the recitation and standing in all four rak'ahs of the Messenger of Allah (peace and blessings be upon him and his family) were equal, except that he would prolong the first rak'ah so that people could arrive. The Prophet (peace and blessings be upon him and his family) would make the men stand in front of the children, the children behind them, and the women behind the children. Whenever he (peace and blessings be upon him and his family) performed sajdah and rose from it, he would say takbeer. Similarly, when after two rak'ahs he sat for tashahhud and then stood up for the third rak'ah, he would say Allahu Akbar.

Ikrimah says: I said to Sayyiduna Abdullah bin Abbas (may Allah be pleased with him): I performed the Zuhr prayer in Batha behind an old man, and this foolish man said twenty-two takbirs; whenever he would prostrate and when he would raise his head from it, he would say the takbir. (Upon hearing this) Sayyiduna Ibn Abbas (may Allah be pleased with him) said: This is the prayer of Abu al-Qasim (peace and blessings be upon him).

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: I saw the Messenger (peace and blessings be upon him) that he would say takbeer at every bowing, rising, standing, and sitting, and when turning to the right and left to say salam (he would turn his blessed face so much that) the whiteness of his cheeks would become visible. Then I saw Sayyiduna Abu Bakr and Sayyiduna Umar (may Allah be pleased with them both) doing the same.
