A Woman should not visit Graves
Question:
What is the ruling on women visiting the graves?
Answer:
It is not permissible for women to visit graves, because the Messenger cursed those women who visit the graves, because they are a trial and a temptation, and the patience of a woman is short. Therefore it is from Allah's Mercy and His Beneficence that He has forbidden them to visit the graves, so that they are neither a source of trial (to others) nor put to trial (themselves). May Allah improve the situation of us all.
