There is no Sacrifice due upon you, if Allâh wills
Question :
I performed the obligation of Hajj two years ago and that was for the first time. On the day of 'Arafah, while I was supplicating to my Lord on that tremendous day, my eyes became red (with crying). Then, when I finished and I wiped my face and my tears with my hands, two hairs fell out into my hand from my eyelashes. That was not intentional, so is there any sin on me for that?
Answer:
May Allâh accept from you and us and multiply your reward and blessing for your eagerness, humility and your deed by which you intended the Face of Allâh. In reference to what you mentioned of eyelash hairs falling out, there is no sacrifice due upon you, if Allâh wills. This is because you did not intend that and it did not occur intentionally. Allâh, the Most High, has pardoned the unintentional mistake and forgetful- ness. May Allâh give you success.
