Musannaf Ibn Abi Shayba 3:5940

Hushaym narrated to us, he said: Mughira informed us, from Abu al-Khayr ibn Tamim ibn Hudhlum, who said: There was darkness in Kufa, so Hani ibn Nuwayra came with a companion of his until they entered upon Tamim ibn Hudhlum, and he was one of the companions of Abdullah [ibn Mas'ud]. They found him praying. He said: So he said to them, "Return to your houses and pray until what you see clears up, for indeed, one used to be commanded to do that."
