(Imām Bukhārī narrates): Muhammad ibn Bashshār narrated to us, he said: Ghundar narrated to us, he said: Shu'bah narrated to us, he said: I heard Qatādah, from Anas ibn Mālik, may Allāh be pleased with him, from the Prophet ﷺ, he said:

Perform rukū' and sujūd with tranquillity, for by Allāh! I see you from behind me — and sometimes he said: from behind my back — when you perform rukū' and when you perform sajdah.
