Leading people in Salah and then noticing traces of blood in one's clothes

Q: I led people in Salah (Prayer) and after finishing Salah I saw spots of blood on my garment. What is the ruling on my Salah? Also, what is the ruling on the Salah of the Ma'mums (people being led by an Imam in Prayer)?

A: If the amount of blood on your garment is only a little, it is excused. However, if it is a large amount but you did not know except after Salah, your Salah and the Salah of those who followed you is valid, but you would have to wash it for the next Salah. If you saw it during Salah and you could take the garment off, you should take it off and then continue your Salah, as the Prophet (peace be upon him) did with his shoes.If you could not take it off, you should leave Salah and appoint someone else to lead the people in Salah, and go to wash it and then resume Salah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
