It is narrated from Sayyiduna al-Miswar bin Makhramah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There is no divorce before marriage."
No one other than Hisham bin Sa'd (may Allah have mercy on him) narrated this hadith from Imam al-Zuhri (may Allah have mercy on him), and no one other than Ali bin al-Husayn (may Allah have mercy on him) related it from Hisham (may Allah have mercy on him), while Ahmad bin Sa'id al-Darimi (may Allah have mercy on him) is alone in narrating it.
