Hadith 9575913 - وَ قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ : "سِبَابُ اَلْمُؤْمِنِ فُسُوقٌ وَ قِتَالُهُ كُفْرٌ وَ أَكْلُ لَحْمِهِ مِنْ مَعْصِيَةِ اَللَّهِ تَعَالَى وَ حُرْمَةُ مَالِهِ كَحُرْمَةِ دَمِهِ".
Hadith.5913 - The Messenger of Allah (swt) (peace be upon him and his family) said:
"Insulting a believer is an act of disobedience, fighting him (a believer) is disbelief, consuming his flesh (backbiting) is a sin against Allah (swt) the Exalted, and the sanctity of his wealth is like the sanctity of his blood."
