Sayyiduna Fadala bin Ubaid (may Allah be pleased with him) narrates: On the occasion of the Farewell Pilgrimage, the Prophet Muhammad (peace and blessings be upon him) said: Shall I not tell you about the believer? The believer is the one from whom people are safe regarding their wealth and lives, and the Muslim is the one from whose tongue and hand other people are safe. The Mujahid is the person who strives with his own self in obedience to Allah Almighty, and the believer is the one who keeps himself away from his faults and sins.
