Musannaf Ibn Abi Shayba 33:468

Waki’ narrated to us, from Abu al-Ashhab, from al-Hasan, who said: Imran ibn al-Husayn was afflicted with an affliction from which he would suffer. He said: So some of those who would come to him said to him, "Indeed, what we see of your condition prevents me from coming to you." He said: "Do not do that, for by Allah, that which is most beloved to me is most beloved to Allah."
