(5) باب قَوْلِ النَّبِيِّ صلى الله عليه وسلم " لَوْ كُنْتُ مُتَّخِذًا خَلِيلاً " قَالَهُ أَبُو سَعِيدٍ
Narrated Abu Sa`id:
The Prophet (ﷺ) said, "Do not abuse my companions for if any one of you spent gold equal to Uhud (in Allah's Cause) it would not be equal to a Mud or even a half Mud spent by one of them."
