Sayyiduna Abu Hurairah, may Allah be pleased with him, narrated that the Messenger of Allah, peace and blessings be upon him, said: Do you think that my face (in prayer) is towards the Qiblah? By Allah, neither your humility is hidden from me nor (when you are) in bowing, I keep seeing you from behind my back.

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) said: Perform bowing (ruku) and prostration (sajdah) properly. By Allah, I see you from behind my back, or he said in this way: from behind my back, when you bow and prostrate (I see you).
