Full Sharh — Mishkat al-Masabih 1757
وَعَنْ عُمَرَ بْنِ الْخَطَّابِ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُعْطِينِي الْعَطَاءَ فَأَقُولُ: أَعْطِهِ أَفْقَرَ إِلَيْهِ مِنِّي. فَقَالَ: «خُذْهُ فَتَمَوَّلْهُ وَتَصَدَّقْ بِهِ فَمَا جَاءَكَ مِنْ هَذَا الْمَالِ وَأَنْتَ غَيْرُ مُشْرِفٍ وَلَا سَائِلٍ فَخذه. ومالا فَلَا تتبعه نَفسك»
English Translation
‘Umar b. al-Khattab said:: The Prophet was giving me something and I asked him to give it to someone who had more need of it than I had, but he said, “Take it, keep it with your property and give it as sadaqa. Take what comes to you from this property when you are neither avaricious nor begging, but in other circumstances do not let your desire go after it.” (Bukhari and Muslim.)
