What is the ruling on one who comes to the mosque to enter Islam but is sent back to another day?

Question:
The questioner from America says: In some of our mosques in America, if a person converts to Islam in the middle of the week, the mosque administration orders him to return and come on Friday, where there is someone to teach him ritual purity and prayer. He asks: What is the guidance in such a case?

Answer:
His Islam is accepted immediately, and he is considered a Muslim. If there is no one to teach him the matters of religion, he waits until someone comes to teach him the matters of religion; there is no harm in that. Yes, but it is not said, “We do not accept your Islam except on Friday,” nor is it not accepted immediately. He is considered a Muslim and welcomed, and the matter of teaching is according to capability and according to the presence of someone to teach him. Yes, and Islamic centers are not devoid of teachers; they are not devoid of scholars. And what does “center” mean? Yes.
