Tahaarah (purity) for one suffering from incontinence
Question

I have an allergy which causes me to sneeze very violently very frequently. Since I became pregnant, I suffer from incontinence whenever I sneeze. As I go to work I cannot change my clothes everytime I need to pray. Can I do wudhu and still pray when I know my clothes have najis on them. Do I need to repeat my prayers on returning home?
Praise be to Allah.Allaah says (interpretation of the meaning):
" and [Allaah] has not laid upon you in religion any hardship" [al-Hajj 22:78] and
" Allaah intends for you ease, and He does not want to make things difficult for you" [al-Baqarah 2:185].
It is sufficient, my sister, if you perform wudoo' before every prayer after the time for it has begun, and do not worry about anything that comes out after that. You could also put a piece of cloth or something similar so that the najaasah (impure substance - in this case urine) does not spread, then throw it away and wash yourself before making wudoo'. We ask Allaah to heal you and give good health to you and to every sick Muslim.
