It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) said: "In the heavens there are two angels; one of them commands severity and the other gentleness, and both are right: they are Jibril and Mika'il. And there were two prophets; one of them commanded gentleness and the other severity, and both were right," and he (peace and blessings be upon him) mentioned Sayyiduna Ibrahim and Sayyiduna Nuh (peace be upon them both): "And I have two companions; one of them commands gentleness and the other severity, and both are right," and he (peace and blessings be upon him) mentioned Sayyiduna Abu Bakr and Sayyiduna Umar (may Allah be pleased with them both).
