It is narrated from Mus'ab bin Abdullah al-Zubayri that Fadalah bin Wahb bin Urwah bin Bujayr bin Malik bin Qays bin Amir bin Layth, whose mother was the daughter of Kaysan bin Amir al-Utwari, had the kunyah Abu Abdullah, and he moved to Basrah.

Abdullah bin Fadalah al-Laythi narrates from his father that he said: The Messenger of Allah (peace and blessings be upon him) taught me (matters of the religion), and among them was that he (peace and blessings be upon him) said: "Guard the five prayers." I said: At these times I have many tasks, so tell me something comprehensive which, if I do it, will suffice for me. So he (peace and blessings be upon him) said: "Guard 'al-asrayn', the two Asrs." I asked: What are the two Asrs? He (peace and blessings be upon him) said: "The prayer before sunrise (Fajr) and the prayer before sunset (Asr)."
