The imam lengthened the sermon in our mosque to more than an hour and a half, so some of the people left. Is he sinful for this?

Question:
May Allah reward you, Your Eminence, father. The questioner says: An imam gave the sermon for us in the Friday prayer, and the duration of the sermon was an hour and a half. So some of the people left the mosque and did not complete listening to the sermon or the prayer. Is the one who left sinful?

Answer:
This imam has done wrong; he has done wrong, and he contradicted the saying of the Messenger (peace and blessings be upon him) in his guidance regarding the Friday sermon. It was that the Messenger (peace and blessings be upon him) had a sermon of a few blessed words, a few blessed words. He did not lengthen the sermon. And he (peace and blessings be upon him) said: "The shortness of a man's sermon and the length of his prayer is a sign of his understanding" . So he is contradicting the guidance of the Messenger (peace and blessings be upon him). As for those who left, they also erred in this. It is obligatory for them to be patient, and after that, they should advise the imam to leave off this lengthening. Yes, because the imam may think that he is pleasing the people and that they love this lengthening, and he does not know that they dislike this thing. So they should advise him. Yes.
