Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) stood on the side of Safa and recited the talbiyah. Masruq (may Allah have mercy on him) said: I have been forbidden from the talbiyah. He replied: But I command you to do it; the talbiyah was a response with which Sayyiduna Ibrahim (peace be upon him) responded.
