وَعَن أبي سعيدٍ وَأبي هريرةَ عَن رسولِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَوْ أَنَّ أَهْلَ السَّمَاءِ وَالْأَرْضِ اشْتَرَكُوا فِي دَمِ مُؤْمِنٍ لَأَكَبَّهُمُ اللَّهُ فِي النَّارِ» . رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيبٌ
Abu Sa'id and Abu Huraira reported God's Messenger as saying, “If the inhabitants of heaven and earth were to share in [shedding] the blood of a believer, God would overturn them in hell.” Tirmidhi transmitted it, saying this is a gharib tradition.
