عَنْ سَعِيدِ بْنِ زَيْدٍ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ مِنْ أَرْبَى الرِّبَا الْإِسْتَطَالَةُ فِي عِرْضِ مُسْلِمٍ بِغَيْرِ حَقٍّ وَإِنَّ هَذِهِ الرَّحِمَ شِجْنَةٌ مِنَ الرَّحْمَنِ فَمَنْ قَطَعَهَا حَرَّمَ اللَّهُ عَلَيْهِ الْجَنَّةَ
It is narrated from Sayyiduna Saeed bin Zaid (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The greatest injustice is that a person violates his brother’s honor without any right, and indeed, maintaining ties of kinship is a branch of the Most Merciful; whoever severs it, Allah Almighty will make Paradise forbidden for him.
