Hadith 23, 40 Hadith Qudsi
On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (ﷺ) 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.

It was related by al-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)
