It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Abu Bakr is the most compassionate towards my Ummah, Umar is the most strict regarding religion among my Ummah, Uthman is the most modest, and Sayyiduna Mu'adh bin Jabal, may Allah be pleased with him, has the greatest knowledge of what is lawful and unlawful.
