Sahih Muslim , Book 32, Hadith 6225 (USC-MSA) ⓘ
Abu Huraira reported Allah's Messenger as saying: Verily. Allah would say on the Day of Resurrection: Where are those who have mutual love for My Glory's sake? Today I shall shelter them in My shadow when there is no other shadow but the shadow of Mine.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكِ بْنِ أَنَسٍ، فِيمَا قُرِئَ عَلَيْهِ عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ، الرَّحْمَنِ بْنِ مَعْمَرٍ عَنْ أَبِي الْحُبَابِ، سَعِيدِ بْنِ يَسَارٍ عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ اللَّهَ يَقُولُ يَوْمَ الْقِيَامَةِ أَيْنَ الْمُتَحَابُّونَ بِجَلاَلِي الْيَوْمَ أُظِلُّهُمْ فِي ظِلِّي يَوْمَ لاَ ظِلَّ إِلاَّ ظِلِّي " .
