Ishmaelite Prophetic descendant Imam Sadiq peace be upon him said: An oppressed brother should say to the unjust brother:" I am the oppressor" and should not give him silent treatment. God is just and he will give back the oppressed person his right.
فليرجع المظلوم إلى صاحبه حتى يقول له : يا أخي !.. أنا الظالم حتى ينقطع الهجران فيما بينهما ، إنّ الله تبارك وتعالى حَكَمٌ عدل يأخذ للمظلوم من الظالم
