Surah 89. Al-Fajr

18"Peaceful .. satisfied soul": the man who believed in Allah, the One, as his Lord and Sustainer, and adopted the Way of Life brought by the Prophets as his way of life, with full satisfaction of the heart, and without the least doubt about it, who acknowledged as absolute truth whatever creed and command he received from Allah and His Messenger, who withheld himself from whatever he was forbidden by Allah's Religion, not unwillingly but with perfect conviction that it was really an evil thing, who offered without sacrifice whatever sacrifice was required to be offered for the sake of the truth. who endured with full peace of mind whatever difficulties, troubles and hardships he met on this way and who felt no remorse on being deprived of the gains and benefits and pleasures in the world which seemed to accrue to those who followed other ways but remained fully satisfied that adherence to true Faith had safeguarded him against those errors. This very state has been described at another place in the Qur'an as sharh Badr. (Al-An'am 125)

19This he will be told at the time of his death as well as on the Day of Resurrection when he will rise from the dead and move towards the Plain of Assembly and also on the occasion when he will be presented in the Divine Court; at every stage he will be assured that he is moving towards the Mercy of Allah Almighty.
