Hadith 5663
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "On Mondays and Thursdays, the gates of Paradise are opened, and forgiveness is granted to every person who does not associate anyone with Allah, except for those two individuals who have severed relations with each other. Allah Almighty says: Leave their matter as it is until they reconcile with each other."
