Musannaf Ibn Abi Shayba 3:950

Mu'adh ibn Mu'adh narrated to us, from Hajib ibn 'Umar, who said: I used to hear my uncle, al-Hakam ibn al-A'raj, asking Dirham Abu Hind about this hadith. He would say: Dirham, I was coming from the market and the people met me returning, as Ma'qil ibn Yasar had led them in prayer, and I was in doubt whether the sun had set or had not set.
