Husayn bin Mihsan says: My paternal aunt (may Allah be pleased with her) told me: I went to the Prophet (peace and blessings be upon him) for some need, and he (peace and blessings be upon him) asked: "Do you have a husband?" I said: Yes. He (peace and blessings be upon him) said: "How are you towards him?" She said: I do not fall short with him, except in what I am unable to do. He (peace and blessings be upon him) said: "Then consider where you stand with him, for he is your Paradise and your Hell."
