Abu Hurairah reported,
"Deeds are presented every Thursday and Monday, and Allah 
forgives on that day every person who does not associate anything with Allah, except a person between whom and his brother there is enmity. It is said, 'Hold back these two until they reconcile, hold back these two until they reconcile.'"

Sahihعن أبي هريرة رفعه قال
تعرض الأعمال في كل يوم خميس واثنين، فيغفر الله عز وجل في ذلك اليوم، لكل امرئ لا يشرك بالله شيئا، إلا امرأ كانت بينه وبين أخيه شحناء، فيقال: اركوا هذين حتى يصطلحا، اركوا هذين حتى يصطلحا.
Muslim narrated it in the Book of Righteousness and Kinship Ties (2565: 36), from Ibn Abu Umar, from Sufyan, from Muslim bin Abu Maryam, from Abu Salih, from Abu Hurairah, and he mentioned it.His saying, "arku," means "delay them." It is said, "rakahu yarkuhu," when he delays something.
