Hadith
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى الصَّنْعَانِيُّ، حَدَّثَنَا الْمُعْتَمِرُ بْنُ سُلَيْمَانَ، عَنْ أَبِيهِ، عَنْ حَنَشٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " الْمُسْلِمُونَ تَتَكَافَأُ دِمَاؤُهُمْ وَهُمْ يَدٌ عَلَى مَنْ سِوَاهُمْ يَسْعَى بِذِمَّتِهِمْ أَدْنَاهُمْ وَيُرَدُّ عَلَى أَقْصَاهُمْ " .
It was narrated from Ibn 'Abbas that the Prophet (ﷺ) said:“The blood of every Muslims is equal, they are one hand against others. The asylum offered by the lowest of them in status applies to them (all), and the return is granted to the farthest of them.”
