Is it permissible to object to some brothers who leave the mosque immediately after prayer without saying the post-prayer remembrances (adhkar), and what should we say to them?

Prescribed remembrances after obligatory prayer are recommended and not obligatory, and they carry great reward. Whoever does not perform them is not sinful but misses out on the reward and following the Sunnah. It is permissible to remind those who are lazy about their virtues in a good manner without reproach. Among its virtues: reciting Ayat al-Kursi after each prayer facilitates entry into Paradise, and saying the tasbeeh, tahmeed, and takbeer thirty-three times each. Pamphlets explaining their virtues can be distributed to the worshippers before prayer.
