(10) باب اتَّقُوا النَّارَ وَلَوْ بِشِقِّ تَمْرَةٍ
Narrated Abu Mas`ud Al-Ansari:
Whenever Allah's Messenger (ﷺ) (p.b.u.h) ordered us to give in charity, we used to go to the market and work as porters and get a Mudd (a special measure of grain) and then give it in charity. (Those were the days of poverty) and today some of us have one hundred thousand.
