It is narrated from Hazrat Abu Ja'far that the Messenger of Allah, peace and blessings be upon him, said: When faith enters the heart, the heart opens up and there is expansion in it. Then he recited this verse { فَمَنْ یُرِدِ اللَّہُ أَنْ یَہْدِیَہُ یَشْرَحْ صَدْرَہُ لِلإِسْلاَمِ }. People asked, "O Messenger of Allah! Is there any sign by which it can be recognized?" He said, "Its sign is turning towards the Hereafter, detachment from the house of deception, and preparing for death before death comes."
