Answered by Shaykh Jamir Meah
Question: Assalamu alaykum
Sometimes I get a cut and put a bandage on to help it heal and prevent the blood from spreading to my clothes. If I took it off, I know blood will likely spread to my clothes. Can I pray with a bandage on, even if I know blood will get on it? Would I have to change it before the next prayer?
Answer: Wa’alaykum assalam, I pray you’re well. Thank you for your question.
Blood is considered filth (najasa) but is however, excused when praying, whether on one’s body or clothes (including plasters and bandages etc.).
Conditions of Exemption
This exemption is on the following conditions:
1. The blood was not caused by the person himself, such as cutting himself on purpose
2. The blood is not mixed with something else, even something pure
3. The blood has not moved from the injured area to a ‘distant’ area of the body or clothes, such as blood from the head landing on the arms or feet (as opposed to a part of the body that is ‘near’ to the injured area, such as the face neck or shoulders in this scenario).
If any these conditions are not fulfilled, only a small amount of one’s own blood is excused.
