Q: I am pregnant. i have morning sickness. Does the vomit break my whudhu and can i pray after i throw up?
A: If the vomit is less than a mouthful, your whudu would not be broken and you can pray with such a whudu. If you vomit more than a mouthfull, you would have to redo your whudu.
May Allah (SWT) bless you with a good pious child, (ameen.)
Allah Certainly Knows Best.
