باب التَّحْرِيضِ عَلَى الصَّدَقَةِ وَالشَّفَاعَةِ فِيهَا
Sahih al-Bukhari 1433

Narrated Asma:

The Prophet (ﷺ) said to me, "Do not withhold your money, (for if you did so) Allah would withhold His blessings from you."

Narrated `Abda:

The Prophet (ﷺ) said, "Do not withhold your money by counting it (i.e. hoarding it), (for if you did so), Allah would also withhold His blessings from you."

حَدَّثَنَا صَدَقَةُ بْنُ الْفَضْلِ، أَخْبَرَنَا عَبْدَةُ، عَنْ هِشَامٍ، عَنْ فَاطِمَةَ، عَنْ أَسْمَاءَ ـ رضى الله عنها ـ قَالَتْ قَالَ لِي النَّبِيُّ صلى الله عليه وسلم ‏"‏ لاَ تُوكِي فَيُوكَى عَلَيْكِ ‏"‏‏.‏ حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، عَنْ عَبْدَةَ، وَقَالَ، ‏"‏ لاَ تُحْصِي فَيُحْصِيَ اللَّهُ عَلَيْكِ ‏"‏
