It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the account of Sayyiduna Umar's (may Allah be pleased with him) acceptance of Islam is as follows; he stated: "One night my sister went into labour «al-makhad» (the pain of childbirth), so I went out of the house (in agitation) and on a bitterly cold night hid myself among the coverings of the House of Allah. Meanwhile the Prophet (peace and blessings be upon him) came and entered the Hatim (al-Hijr), wearing his sandals. Then he (peace and blessings be upon him) prayed for as long as Allah willed and then turned away from there." Sayyiduna Umar (may Allah be pleased with him) relates: "I heard from him (peace and blessings be upon him) (in his recitation) speech the like of which I had never heard before. So I came out (from the coverings) and followed him (peace and blessings be upon him). He (peace and blessings be upon him) asked: 'Who is this?' I said: 'Umar.' He (peace and blessings be upon him) said: 'O Umar, will you not leave me alone, neither by night nor by day?'" Sayyiduna Umar (may Allah be pleased with him) says: "I feared that he (peace and blessings be upon him) might supplicate against me, so I immediately said: «Ashhadu an la ilaha illallah, wa annaka Rasul Allah» 'I bear witness that there is no god worthy of worship but Allah, and that you are indeed the Messenger of Allah.' He (peace and blessings be upon him) said: 'O Umar, keep it hidden (for now).' I said: 'Never! By the One who sent you with the truth, I will certainly declare it openly, just as I declared polytheism openly.'"
