Question: Assalamu aleykum.
 If I get a another person’s or animal’s blood, urine, or feces on my body, will that break my wudu?
 What if you see that you have one minute left before the current prayer time is over. You are in a state of wudu but you know that you can not finish the first raka of the current prayer before the time is over. Should you start prayer or wait until the time is over and pray it as a qada?
Answer: Wa alaikum assalam wa rahmatullahi wa barakatuh,
I pray that you are in the best of health and faith, insha’Allah.
 The legal cause for the nullification of your wudu is the exiting of filth from your person. As for being affected by filth from another person or an animal, this would follow the rules of removing filth. Thus you would wash away the filth, yet your wudu would remain unaffected.
 You should complete the prayer as normal because the exiting of the time is only invalidating at Fajr. Please see: Is My Prayer Valid if I Finish Praying Outside its Respective Prayer Time?

And Allah alone gives success.
