1 hadith
Hadith 1883
Mus'ab bin Sa'd bin Abi Waqqas narrates: When I used to perform prayer, I would do tatbeeq and place both my hands between my knees. My father, Sayyiduna Sa'd (may Allah be pleased with him), saw me doing this and said: We used to do this before, then we were forbidden from it, and we were commanded to place (our hands) on the knees.
