40 Hadith Qudsi
On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (peace and blessings of Allah be upon him) said:
"Allah (mighty and sublime be He) says:
'My faithful servant's reward from Me, if I have taken to Me his best friend from amongst the inhabitants of the world and he has then borne it patiently for My sake, shall be nothing less than Paradise.'"
[Bukhari]
