Does blood coming from the chest during prayer invalidate the prayer?

The questioner : The questioner says: I was praying the 'Isha' prayer this night, and I coughed, and blood came out of my chest such that it soiled the handkerchief and the pocket. Is my prayer valid?

The Shaykh : The answer is: Yes, your prayer is valid, and you owe nothing. This is because the view is that if blood comes out from other than the two passages, it does not invalidate the wudu', even if it is a lot. Accordingly, if a person weakens and blood comes out of him, even a lot, or if he vomits, even if it is a lot, his wudu' is not invalidated by that. And if the wudu' is not prolonged, the prayer is not prolonged either. And what happened to you due to the cough is also a small amount of blood, so carrying it in your prayer does not harm you. If you wipe it with the handkerchief and carry it in your prayer, it does not harm you.
