Question: Some people say that if the Day of ‘Arafah (9 Dhul-Hijjah) falls on a Friday, then it is as if someone has performed 7 Hajjs (i.e. he is rewarded as having done so). Is there any evidence from the Sunnah regarding this?
Response: There is no authentic evidence regarding this. (However), some people (also) believe this equates to (having performed) 70 Hajjs or 72 Hajjs, and this is also incorrect.
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet (sal-Allaahu `alayhe wa sallam) and his family and his companions.
