Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "On Mondays and Thursdays, the gates of Paradise are opened, and Allah forgives every Muslim servant who does not associate anything with Allah, except for the person who has enmity with his brother. It is said: Defer the matter of these two until they reconcile, defer the matter of these two until they reconcile."
