Spiritual retreat (i'tikaf) of the sick person in his room

Question:
Abu Khalid asks, Shaykh, about i'tikaf. If a person is sick and prays in his home due to his severe illness, and he wants to perform i'tikaf, does he perform it in his room?

Answer:
No, i'tikaf is not valid except in the mosque, . The Prophet (peace and blessings be upon him) used to perform i'tikaf in the mosque, and the Companions and those who came after them used to perform i'tikaf in the mosques. Therefore, it is not permissible to perform i'tikaf outside the mosques, because this contradicts the Sunnah, and because it cuts off the congregational prayer. So either he abandons the congregational prayer, which is abandoning an obligatory duty,
or he goes out for the congregation, which is incompatible with i'tikaf due to the frequent entering and exiting. Entering and exiting is incompatible with i'tikaf, because i'tikaf is the continuous staying in the mosque for the worship of Allah (Mighty and Majestic). However, this person is considered unable, and his intention is good, and he will be rewarded for it. As for performing i'tikaf in his room, this is not permissible. Yes.
