You ask about the blood that is on wounds and that collects on pimples, for example on the face and elsewhere, is it pure or impure?

As for the small amount of blood that comes out of a person, which might come from his nails or from a nosebleed or something minor.

Or a pimple that might be on his body and it bleeds and so on, we say this does not harm a person.

It has been authentically reported from Abu Huraira, may Allah be pleased with him, and also from Abdullah ibn Umar, that he put his fingers in his nose and all ten became wet with blood while he was praying.

It was also reported from some of the early generations, as Al-Hasan said: People have always prayed with their wounds.

It was also reported by Ibn Majah in the narration of Aisha, may Allah the Exalted be pleased with her, that Usama ibn Zayd stumbled at the door and injured his face, so the Messenger of Allah ﷺ came to him.

So he sucked the blood and then spat it out, and the Messenger of Allah ﷺ said: If Usama had been a girl, I would have adorned and beautified her until I married her off.

Until I married her off, and what is meant by this.

That the Prophet, peace be upon him, could not have sucked and swallowed into his stomach, into his mouth—he did not let anything forbidden enter his stomach.

Something impure, and for this reason we say this is evidence of its purity. As for what relates to impurity and flowing blood, the most likely view is that, and some consider all blood to be impure.

In general, but we say this is what the evidence supports: minor wounds that come from a person's nails or, for example, from a scar.

Or from pimples and the like, this does not harm a person and there is nothing upon him, in fact, it does not even break wudu if it comes out, and Allah knows best.
