Al-Mu'jam al-Awsat 3130 — Sayyiduna Mu'awiyah bin Abi Sufyan sent

Atiyyah bin Qays al-Kilabi (may Allah have mercy on him) narrates that Sayyiduna Mu'awiyah bin Abi Sufyan (may Allah be pleased with him) sent a proposal of marriage to Umm al-Darda' (may Allah have mercy on her) after the death of Sayyiduna Abu al-Darda' (may Allah be pleased with him). Umm al-Darda' (may Allah have mercy on her) said: "Indeed, I heard Sayyiduna Abu al-Darda' (may Allah be pleased with him) say that he heard the Messenger of Allah (peace and blessings be upon him) say: 'Any woman whose husband dies, and then she marries (another) after him, she will belong to the last of her husbands.' And I will never prefer you over Sayyiduna Abu al-Darda' (may Allah be pleased with him)." Upon this, Sayyiduna Mu'awiyah (may Allah be pleased with him) wrote to her: "Then devote yourself to fasting, for it is a means of curbing (the desires of the self)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one other than al-Walid narrated this hadith from Abu Bakr bin Abi Maryam."
