6. A number of our people have narrated from Ahmad Ibn Muhammad Ibn Khalid from Sharif Ibn Sabiq from al-Fadl Ibn Abu Qurrah from Abu ‘Abdillah (al-Sadiq) (as) that Rasulullah (sw) said: "The best time to supplicate to Allah (azwj) is during the pre-dawn hours (Al-Asḥār)." Then he recited this verse from the words of Ya'qub (as): «I will ask forgiveness for you from my Lord» (12:98) and he (the Prophet) said, "He delayed them until pre-dawn hours (to pray for them)."
