Hadeeth Qudsi 23:

On the authority of AbuHurayrah (may Allah be pleased with him), who said that the Messengerof Allah  said: Allah will say on the Day of Resurrection:

Where are those who love oneanother through My glory? Today I shall give them shade in My shade, itbeing a day when there is no shade but My shade.

It was related by al-Bukhari(also by Malik).
