Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that the Messenger of Allah (peace be upon him) used to recite the Qur'an to us. When he (peace be upon him) would recite a surah in which there was a verse of prostration, he (peace be upon him) would perform sajdah and we would also perform sajdah with him (peace be upon him), to the extent that some of us would not find space to place our foreheads.
