“Once I asked Abu ‘Abdillah (a.s.) about the words of Allah, the Most Majestic, the Most Holy, ‘And whoever rejects belief, his work has become worthless...’ (5:5) The Imam said, ‘ It is one who abandons the deed he has affirmed (believed in.)’ I then asked, ‘What is the extent of abandoning the deed? Until he leaves it entirely?’ The Imam said, ‘Among them is the one who intentionally abandons prayer, not out of drunkenness or illness.’”
