Muhammad bin · The Book of Fasting

Tho month is thus and thus, and thus, i. e. ten, ten and nine.

I asked Jabir b. 'Abdullah (Allah be pleased with both of them) as he was circumambulating the House (Ka'ba) whether the Messenger of Allah (ﷺ) had forbidden the fasting on Friday, whereupon he said: Yes, by the Lord of this House.

"The Messenger of Allah used to fast Sha`ban and Ramadan, and he made sure to fast on Mondays and Thursday."
