عَنْ أَبِي خِرَاشٍ السُّلَمِيِّ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ سَمِعَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ ((مَنْ هَجَرَ أَخَاهُ سَنَةً فَهُوَ كَسَفْكِ دَمِهِ))
It is narrated from Sayyiduna Abu Khirash Salmi, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Whoever abandons his brother for a year, it is as if he has shed his blood.
