Musnad Abu Ya'la al-Mawsili 165:14

Mansur ibn Abi Muzahim narrated to us, Umar ibn Shabib narrated to us, from Yusuf al-Sabbagh, from al-Husayn—and I do not know him to be except from the Prophet, may Allah bless him and grant him peace—who said: "Whoever witnesses a matter and dislikes it, he is like one who was absent from it. And whoever is absent from a matter and is pleased with it, he is like one who witnessed it."
