Muharib (may Allah have mercy on him) said that the Messenger of Allah (peace and blessings be upon him) said: "Of the things Allah, the Lord of Might, has made lawful, the most disliked by Allah is divorce."
This is the hadith of Abu Dawud, and it is mursal. In the narration of Ibn Abi Shaybah it is connected (mawsul) from Abdullah bin Umar, but I do not think he preserved it accurately.
