Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated Ibn Juraij (Radi-Allahu ‘anhu):
Ikrima bin Khalid asked Ibn ‘Umar about performing ‘Umra before Hajj. Ibn ‘Umar replied, “There is no harm in it.” ‘Ikrima said, “Ibn ‘Umar also said, ‘The Prophet (Sallallahu ‘Alaihi Wa Sallam) had performed ‘Umra before performing Hajj.’”
