Does donating blood platelet invalidate ablution?
Blood platelets are the cells that existin the blood and stop bleeding by forming thwe blood clots. It is also known as white blood among the people. Blood platelet is obtained in two ways:
- a) By method of normal blood donation: In this method, minor ablution is invalidated as normal blood donation is involved.
- b) By apheresis device: In this method, blood is taken from an arm of the volunteer with apheresis device, the platelets in it are sorted out and given back to the volunteer from the other arm. Although the blood taken is given back to the same person from the other arm, ablution is invalidated as the blood comes out of the body.
These rulings are according to the Hanafi scool. As for the Shafi’is, giving blood does not invalidate ablution (See. Mawardi, al-Hawi, I, 199-200; Shirbini, Mughnil’l-muhtaj, I, 64).
