Once I said, "O Messenger of Allah ﷺ! 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 ﷺ said, "Give in charity and do not withhold it; otherwise Allah will withhold it back from you . "
قُلْتُ يَا رَسُولَ اللَّهِ مَا لِي مَالٌ إِلاَّ مَا أَدْخَلَ عَلَىَّ الزُّبَيْرُ فَأَتَصَدَّقُ قَالَ تَصَدَّقِي وَلاَ تُوعِي فَيُوعَى عَلَيْكِ
