(Imām Bukhārī narrates): Qutaibah ibn Sa'īd narrated to us, he said: Bakr narrated to us, from Ja'far ibn Abī Rabī'ah, from al-A'raj, from 'Abdullāh ibn Mālik ibn Buhainah, he narrated that:

the Messenger of Allāh ﷺ led us in the Zuhr prayer, so he stood up although he ought to have sat, and when the prayer came to an end, he performed two sajdahs while sitting.
