(Imām Bukhārī narrates): Ismā'īl narrated to us, he said: Imām Mālik narrated to me, from Abī al-Zinād, from al-A'raj, from Abū Hurairah, may Allāh be pleased with him, that the Messenger of Allāh ﷺ said:
Do you think that my qiblah is here? By Allāh! Neither your rukū' is hidden from me, nor your khushū' (is hidden), and indeed I surely see you even from behind my back.
