On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (peace and blessings of Allah be upon him) said:
"Allah will say on the Day of Resurrection:
'Where are those who love one another through My glory? Today I shall give them shade in My shade, it being a day when there is no shade but My shade.'"
[Bukhari (also by Malik).]
عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ :
"إِنَّ اللَّهَ تَبَارَكَ وَتَعَالَى يَقُولُ يَوْمَ الْقِيَامَةِ: أَيْنَ الْمُتَحَابُّونَ بجَلَالِي؟ الْيَوْمَ أُظِلُّهُمْ فِي ظِلِّي يَوْمَ لَا ظِلَّ إِلَّا ظِلِّي"
رواه البخاري (وكذلك مالك)
