Sahih al-Bukhari, Hadith 2590 ⓘ
Narrated Asma: Once I said, "O Allah's Messenger! I have no property except what has been given to me by Az-Zubair (i.e. her husband). May I give in charity?" The Prophet said, "Give in charity and do not withhold it; otherwise Allah will withhold it back from you. "
حَدَّثَنَا أَبُو عَاصِمٍ، عَنِ ابْنِ جُرَيْجٍ، عَنِ ابْنِ أَبِي مُلَيْكَةَ، عَنْ عَبَّادِ بْنِ عَبْدِ اللَّهِ، عَنْ أَسْمَاءَ ـ رضى الله عنها ـ قَالَتْ قُلْتُ يَا رَسُولَ اللَّهِ مَا لِي مَالٌ إِلاَّ مَا أَدْخَلَ عَلَىَّ الزُّبَيْرُ فَأَتَصَدَّقُ. قَالَ " تَصَدَّقِي، وَلاَ تُوعِي فَيُوعَى عَلَيْكِ " .
