:salam2: There is going to be a drive for bone marrow donation for this little 6 year old girl with leukemia at my daughters school. She is suffering and if she does not have it in 2 months, they say she will not make it(Allah knows best). I was considering doing this test to see if I am a match for her, but just wanted to know the ruling on this inshallah. The drive is this Saturday, so if anyone can give some daleel on this inshallah. Jazakallahu Khairan!
