Ala bin Ziyad narrates: A man asked Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him): Which believers are the best in Islam? He replied: "The best believers in Islam are those from whose tongue and hand other Muslims are safe. Striving against one's own self for the sake of Allah Almighty is the best jihad, and contending with one's own self and desires for the sake of Allah Almighty is the best migration (hijrah)." The man asked: O Abdullah bin Umar! Are these your words or those of the Messenger of Allah (peace and blessings be upon him)? He replied: The Messenger of Allah (peace and blessings be upon him) said these.
