It was narrated from ‘Abdullah bin Busr that the Messenger of Allah (ﷺ) said: “Do not fast on Saturdays apart from days when you are obliged to fast. If anyone of you cannot find anything other than grape stalks or the bark of a tree, let him suck on it.”
It was narrated from Ibn ‘Abbas that the Messenger of Allah (ﷺ) said: “There are no days during which righteous deeds are more beloved to Allah than these days,” meaning the (first) ten days of Dhul- Hijjah. They said: “O Messenger of Allah! Not even Jihad in the cause of Allah?” He said: “Not even Jihad in the cause of Allah, unless a man goes out with himself and his wealth and does not bring anything back.”
