What are the recommended books for the imam to read after the prayer

Question : Shaykh Muhammad, this questioner says: What books do you recommend for discussing the congregation in the mosque, especially those where the number of worshippers is large?

Answer : Praise be to Allah, Lord of the worlds, and I send prayers and peace upon our Prophet Muhammad, and upon his family and his Companions, and upon those who follow them with excellence until the Day of Judgment. What the imam who reads to his congregation or speaks to them should do is choose what is appropriate for the time and the condition of the people.
So in Ramadan, he should choose from the books what discusses fasting and its rulings, standing in night prayer and its rulings, and the like.
And in the ten days, for example, he speaks about the virtues of the ten days, the virtues of their nights and standing in prayer, and the like. And when the Festival of Breaking the Fast is near, he speaks about the alms given at the end of Ramadan and its rulings, the time for giving it, its amount, and its type. The important thing is that he should consider the conditions of the people and the time in which he is speaking. In the days of the Festival of Sacrifice, he speaks to them about the 'Id sacrifice and its rulings, what is sacrificed, and its time. In the days of traveling for Hajj, he speaks about Hajj and its rulings, its conditions, its manner, and the like. In days when there is much gossip, he speaks about the ruling on gossip, warns against it, explains its bad effects, and explains the ruling on backbiting and its effects, the ruling on talebearing and its effects, and the like. The successful person is the one who looks deeply into the conditions of the people and speaks to them with what is appropriate for those conditions.
