Abdullah narrated to us, Khalaf ibn Hisham al-Bazzar and Abu Bakr ibn Abi Shaybah narrated to us, they said: Abu al-Ahwas narrated to us, from Abu Ishaq, from al-Ayzar ibn Hurayth, from Abu Basir, who said: Ubayy said: The Messenger of Allah, peace and blessings be upon him, led us in the dawn prayer, and when he finished the prayer, he saw that the people in the mosque were few, so he said: "Is so-and-so present?" We said: Yes, until he counted three men, then he said: "There is no prayer heavier upon the hypocrites than the last night prayer (Isha) and the dawn prayer," and he mentioned the rest of the hadith at length.
