Does the imam sin if he delegates the leading of the mosque to someone and goes to perform 'Umrah in the last ten days?

The questioner : This questioner says: I am the imam of one of the mosques, and I delegated one of my colleagues and went to spend the rest of the ten days in Ramadan. Is there a sin on me for that?

The Shaykh : There is no sin on him if the responsible authorities agreed to it. He should entrust the people of the mosque to the one he appointed as his deputy. However, he erred in this action. Because remaining in his mosque and performing his duty is better for him than going to Makkah to perform an 'Umrah that is not obligatory upon him.
Therefore, we say to our brothers the imams: remaining as imams in your mosques is better for you than going to Makkah. If you refuse to do anything but come for the 'Umrah, then go for the 'Umrah for a day and a night, and that is sufficient as a reward, if Allah wills.
Likewise, it is wrong for one to leave his mosque to perform i'tikaf (spiritual retreat) in another mosque. Because i'tikaf is a recommended practice (sunnah), and performing the duty of one's position is obligatory. Yes. So it is not befitting for a person to leave an obligatory act to perform a recommended practice. And how many people do this. That is, they perform the recommended practice while neglecting the obligatory. Until some people ask, saying: I want to borrow money, as a loan, in Ramadan to give it as charity. It is said: This is foolishness. To burden your conscience with this debt in order to give voluntary charity that is not prescribed for you. Because performing your obligatory maintenance for yourself and your family is better than giving charity to distant relatives. Thank you, Honorable Shaykh, for your kindness.
