Abdullah bin Sharik Amiri says: I heard that Sayyiduna Abdullah bin Umar, Sayyiduna Abdullah bin Abbas, and Abdullah bin Zubair were asked about performing Umrah before Hajj, so all of them said: Yes, this is the Sunnah of the Messenger of Allah (peace and blessings be upon him). When you reach Makkah Mukarramah, perform the Tawaf of the House of Allah and the Sa’i between Safa and Marwah, and then come out of Ihram (thus this will be your Umrah), even if this act is done one day before Arafah. After that, you should enter into Ihram for Hajj. In this way, Allah Almighty will grant you the opportunity to perform both Hajj and Umrah.
