On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (Sal Allahau Alaihi Wa Aalihi Wasallam) 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 brings a day when there is no shade by My shade.
It was related by al-Bukhari (also by Malik).
