On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (peace 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. It was related by al-Bukhari (also by Malik).
