Q) Is ‘Umrah mustahabb during the last ten days of Ramadaan?
A) Praise be to Allaah.
The Prophet (peace and blessings of Allaah be upon him) encouraged us to perform ‘Umrah in the month of Ramadaan. Al-Bukhaari (1782) and Muslim (1256) narrated that Ibn ‘Abbaas said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “ ‘Umrah in Ramadaan is equivalent to Hajj.”
This includes all of Ramadaan, not just the last ten days.
And Allaah knows best.
