The ruling on leaving the mosque after the obligatory prayer

Question:
Some people say that the questioner deprives himself of good. As soon as he finishes the prayer, he does not perform the regular voluntary prayers (rawatib), nor does he pray for the dead, but he leaves immediately after the obligatory prayer ends.

Answer:
This is depriving oneself of good, unless he has a need that requires him to leave, in which case there is no harm. However, if he leaves out of a desire to avoid good and laziness regarding the remembrance of Allah and obedience, then this is depriving oneself of good. He must abandon this bad habit and accustom himself to sitting in the mosque and staying after the prayer for the remembrance of Allah the Exalted and Majestic, and to engage in the prescribed dhikr: the glorifications of tasbih, tahmid, and takbir, each word thirty-three times, and then to complete the hundred by saying: "There is no god but Allah, He has no partner, to Him belongs the dominion and to Him belongs the praise, and He is over all things competent." Then, after that, he may leave if he wishes. Yes.
