To make the Heart Tender (Ar-Riqaq)

Bukhari :: Book 8 :: Volume 76 :: Hadith 525

Narrated Abu Huraira:

The Prophet said, "The people will fall down unconscious at the time when they should fall down (i.e., on the Day of Resurrection), and then I will be the first man to get up, and behold, Moses will be there holding (Allah's) Throne. I will not know whether he has been amongst those who have fallen unconscious."
