Mukhtasar Sahih Bukhari — Hadith 2098

Narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Allah Almighty says: 'When I take away a beloved thing of a believing servant from the world (such as a son, brother, etc.) and he remains patient over it, then his reward with Me is nothing except Paradise (that is, he will be granted Paradise).'"
