Hadith 743
Ibn Umar said: When the Messenger of Allah ﷺ stood at the end of two rak’ahs, he uttered the takbir (Allah is most great) and raised his hands.
Hadith 744
Narrated Ali ibn Abu Talib: When the Messenger of Allah ﷺ stood for offering the obligatory prayer, he uttered the takbir (Allah is most great) and raised his hands opposite to his shoulders; and he did like that when he finished recitation (of the Quran) and was about to bow; and he did like that when he rose after bowing; and he did not raise his hands in his prayer while he was in his sitting position. When he stood up from his prostrations (at the end of two rak'ahs), he raised his hands likewise and uttered the takbir (Allah is most great) and raised his hands so as to bring them up to his shoulders, as he uttered the takbir in the beginning of the prayer.
Hadith 745
Malik bin al-Huwairith said: I saw the Prophet ﷺ raise his hands when he uttered the takbir (Allah is most great), when he bowed and when he raised his head after bowing until he brought them to the lobes of his ears.
Hadith 746
Narrated Abu Hurairah: If I were in front of the Prophet ﷺ, I would see his armpits. Ibn Muadh added that Lahiq said: Do you not see, Abu Hurairah could not stand in front of the Prophet ﷺ while he was praying. Musa added: When he uttered the takbir, he raised his hands.
Hadith 747
Narrated Abdullah ibn Masud: The Messenger of Allah ﷺ taught us how to pray. He then uttered the takbir (Allah is most great) and raised his hands; when he bowed, he joined his hands and placed them between his knees. When this (report) reached Saad, he said: My brother said truly. We used to do this; then we were later on commanded to do this, that is, to place the hands on the knees.
