حدثنا علي بن محمد حدثنا وكيع عن الأعمش عن مجاهد عن عبد الرحمن بن أبي ليلى

Sourcing, [sahih] Ahmad narrated it, 5/157, from Waki, with this wording, and Busiri graded it sahih. Amr bin Maymun also narrated it, as did Nasai in Kubra, no. 9842, and Ibn Hibban in his Sahih, no. 2339, and Abdul-Rahman bin Ghanm (Ahmad) from Abu Dharr, with this wording. The hadith has many corroborating narrations.
