Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever has a daughter and gives her a good upbringing, gives her a good education, and is generous to her from the blessings that Allah has granted him, she will be a protection and a shield for him from Hell."
