"Everyone shall taste death. And only on the Day of Resurrection shall you be paid your wages in full. And whoever is removed away from the fire and admitted to Paradise, he indeed is successful. The life of this world is only the enjoyment of deception (a deceiving thing)."
(Qur'an Al-Imran 3:185)
After the Prophet (saw) would bury the deceased he would stand by the grave and say: 'Seek forgiveness for your brother and pray that he remains firm, for he is now being questioned.'
