Is it permissible for a person to intend i'tikaf (spiritual retreat in the mosque) only during the time of attending the lesson, or only during the time of entering the mosque for the night prayer?

Question:
He says: Honorable Shaykh, may Allah grant you success, is it permissible for a person to intend i'tikaf (spiritual retreat in the mosque) only during the time of attending the lesson, or only during the time of entering for the night prayer in Ramadan, on the condition that his i'tikaf ends when the night prayer or the lesson ends?

Answer:
The jurists have mentioned that he may do so, but there is no evidence for it, that every time you enter the mosque you intend i'tikaf. However, sitting in the mosque and waiting for the prayer has great virtue. Yes.
