It is narrated from Abd al-Rahman bin Yazid bin Jariyah that the Messenger of Allah (peace and blessings be upon him) one day prayed Fajr in the darkness (of early dawn), then on a day after that he prayed it when the light had spread, and then he said: "Between these two is the (Fajr) time."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Zuhri except Abd al-Rahman bin Namir, and al-Walid is alone in narrating it."
