Musnad Abu Ya'la al-Mawsili 134:17

Ibrahim narrated to us, Abu Usamah narrated to us, al-A’mash narrated to us, that Anas bin Malik recited this verse: "Indeed, the rising of the night is stronger in impact and more correct in speech." A man said to him, "We only recite it as 'more upright in speech' (aqwamu qila)." Anas said, "Indeed, 'more upright' (aqwamu), 'more correct' (aswabu), 'more suitable' (ahya'u), and things similar to this are one and the same."
