After iftaar, he goes and prays in congregation in the mosque, and after the prayer he prays two rak'ahs (the regular Sunnah of Maghrib).
Then he goes back home and eats whatever is available – without eating too much.
Then he looks for a suitable way for himself and his family to spend this time, whether reading a book of stories, or a book on practical rulings, or a quiz, or permissible conversation, or any other useful idea that is of interest to the members of the family and will distracts them from the haraam things that appear in the media which regard this as their prime time, so you find the media transmitting their most attractive programs at that time, that may contain immoral and obscene material.
Strive to turn away from that, and fear Allaah with regard to your “flock” (i.e., your family) concerning whom you will be questioned on the Day of Resurrection, so be prepared to answer the questions.
