It was
narrated from Abu Hurairah that the Prophet (ﷺ) used to fast
on
Mondays and Thursdays. It was said:
“O Messenger of Allah, why do
you fast on Mondays and Thursdays?” He said: “On Mondays and
Thursdays
Allah forgives every Muslim except two who have forsaken
one another.
He says: ‘Leave these two until they reconcile.’”
