What is the ruling on delaying the prayer, such as the Zuhr prayer, due to the time of a lecture or class in a school, for example, from another congregation in the same mosque?

The questioner : What is the ruling on delaying the prayer, such as the Zuhr prayer, due to the time of a lecture or class in a school, for example, for another congregation in the same mosque?

The Shaykh : Is the mosque a general mosque, not specific to the school?

The questioner : No, it is specific to the school, and all obligatory prayers are performed in it, and ... .

The Shaykh : But it is a mosque, not an absolute mosque, rather it is a school mosque.

The questioner: Yes.

The Shaykh : So, after this clarification, you mean a prayer place (musalla) and not a mosque; because a mosque has specific rulings, among which is that it should not be converted one day into a hall, into a school classroom, or that it be demolished, for example, and something else built. So, if it is a school mosque, it is a musalla, and in that case, the rulings of mosques do not apply to musallas that are established, whether they are in schools, hospitals, companies, or musallas; so the rulings that apply to mosques do not apply to them. For example, if a person enters this musalla, it is not obligatory for him to pray two rak'ahs before sitting, unlike general mosques. Also, what you were referring to: it is prescribed in this musalla to have multiple congregations, as long as it is not a general mosque with a regular imam and a regular mu'adhdhin, and attended by whoever wishes from passersby and neighbors, and the like. So, in that case—as I said at first—no ruling from the rulings of mosques applies to it, including the dislike of repeating congregations in mosques. This dislike does not apply here. But the thing that can be said on this occasion is two matters:
The first matter: It should be that the curricula of all schools be one hundred percent Islamic. This includes training students to leave the classroom and the school to the nearest mosque to them, where they pray with the Muslim congregation, and not separating from them by praying the congregation in their musalla. This is first. And without a doubt, achieving such a matter in these times, which are controlled by rulings that are not based on the Book of Allah and the Hadith of the Messenger of Allah, is not an easy matter. And until this matter is achieved—and may it be soon—no less than the school principal should be directing and organizing to increase the single congregation and reduce the multiple congregations. Is the answer clear? Meaning, if the number of students, for example, is one thousand students, the curriculum should be based on all of them gathering at one time and praying behind one imam. If this is difficult—and it may be said so—as it was said: "O my Lord, some of the evil is easier than some." So instead of being ten congregations, or five congregations, or four congregations, let them be two congregations. The important thing is to establish a curriculum to reduce these congregations about which the question was asked. And although the answer is that it is permissible as long as this multiplicity is not in the general mosque, but rather in the musalla, nevertheless, the one in charge of such a school should be keen to gather the students behind one imam; because it is established by the Shari'ah that the virtue of the congregation increases in virtue as the number of worshippers increases, and the opposite is the opposite. As indicated by his saying (peace and blessings be upon him): And so on; so the more the number, the better the congregation.
Other than that?
