al-Nadr bin Shumayl al-Maazni النضر بن شميل المازني أبو الحسن النحوي · The Book of Fasting

"The Messenger of Allah said; 'DO not be confused by the Adhan of Bilal, or by this whiteness, until dawn appears like this" - meaning horizontally. (One of the narrators) Abu Dawud said: "And he spread out his hands gesturing to the right and left."

"The Messenger of Allah said: 'Whoever fasts Ramadan out of faith and in the hope of reward, he will be forgiven his previous sins."'

"The Messenger of Allah used to be keen to fast on Mondays and Thursday."
