OBLIGATIONS OF ONE MUSLIM TO ANOTHER H 235 "Muslims are brothers to one another. He should neither cheat, lie, nor humiliate him. Everything belonging to a Muslim is forbidden to another Muslim; his property and his blood.(Pointing to his heart he said:) Piety is here. It is evil for a person to look down upon his brother Muslim." R 235 Tirmidhi with a chain up to Abu Hurairah who related that the Prophet, praise and peace be upon him, said this.
234- وعن أَبي هريرة رضي الله عنه ، قَالَ : قَالَ رَسُول الله صلى الله عليه وآله وسلم : "المُسْلِمُ أخُو المُسْلِمُ ، لاَ يَخُونُهُ ، وَلاَ يَكْذِبُهُ ، وَلاَ يَخْذُلُهُ ، كُلُّ المُسْلِمِ عَلَى المُسْلِم حَرَامٌ عِرْضُهُ وَمَالهُ وَدَمُهُ ، التَّقْوى هاهُنَا ، بحَسْب امْرىءٍ مِنَ الشَّرِّ أنْ يَحْقِرَ أخَاهُ المُسْلِم" رواه الترمذي ، وَقالَ : "حديث حسن" .
