Sayyiduna Ammar bin Yasir (may Allah be pleased with him) relates that the Messenger of Allah (peace and blessings be upon him) intended to divorce Hafsah (may Allah be pleased with her), and Jibril (peace be upon him) came and said: "Do not divorce her, for she fasts much and stands in prayer much, and she will be your wife in Paradise as well."
