History of Jumu’a: Nabi SAW could not perform Jumu’a in Makkah Mukarramah due to the restrictions placed upon him by the mushrikeen of Makkah.However,He SAW ordered Mus’ab bin Umair RA (who had been sent to Medinah Munawwarah as a teacher to those who had accepted Islam),to lead the people in Jumu”ah salaah at the time of Thur.Thus Mus’ab RA was the first to lead Jumu’a and this continued untill Nabi SAW migrated to Medinah Munawwarah
