اَلسَّلَامُ عَلَيْكُمْ dear ustadh, I suffer from incontinence and I usually wrap toilet paper to protect my clothes. At work today there was no paper and most likely a few drops fell on my clothes. I intended to change after work but I forgot and did salah like this. Is it valid? جزاك الله خيراً

Ustadh AbdulAziz al-Haqqan

If you did not know of the impurity, or you knew and then forgot and did not remember until after the prayer, the prayer is valid, and this is what Imam Ibn Baz held. If a person knows it is there and prays in it deliberately, the prayer is not valid and it is repeated.
