Is it permissible to pray the night prayer after the farewell tawaf?

Question:
May Allah reward you. The questioner says: The bus departs for Syria tomorrow evening, if Allah wills. I wished to attend the completion of the recitation of the Noble Qur'an. How can I attend it? I have learned that our last act is the tawaf. Can I perform tawaf between Maghrib and 'Isha' so that I can pray the night prayer? Please guide me so that I can attend the completion of the recitation of the Qur'an.

Answer:
Yes, this depends on your circumstances. I do not know what your circumstances are; it is up to you. If you are able to perform tawaf between Maghrib and 'Isha', pray the night prayer, and attend the completion, that is good. You combine the two benefits: the reward of tawaf and the reward of prayer and attending the supplication.
As for if you are not able, if you are not able to attend, attending the prayer is better, without doubt. Attending the supplication is better. The tawaf is not obligatory. The farewell tawaf in 'Umrah is not obligatory. This is in Hajj; the farewell tawaf is one of the obligations of Hajj, and it is not obligatory in 'Umrah. But if you can manage both, that is better.
Otherwise, the night prayer and attending the supplication are better than tawaf. Even if you do not perform tawaf, there is no blame on you, because you do not have an obligatory farewell tawaf.
