It was narrated from Abu Musa that the Prophet said:"Every Muslim must give charity." It was said: "What if he cannot find (anything to give)? "He said: "Let him work with his hands and benefit himself and give in charity." It was said: "What if he cannot do that?" He said: "Let him help someone who is in desperate need." It was said: "What if he cannot do that?" He said: "Let him enjoin good." It was said: "What if he cannot do that? He said: "Let him refrain from doing evil, for that is an act of charity."
أَخْبَرَنِي مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا خَالِدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي ابْنُ أَبِي بُرْدَةَ، قَالَ سَمِعْتُ أَبِي يُحَدِّثُ، عَنْ أَبِي مُوسَى، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " عَلَى كُلِّ مُسْلِمٍ صَدَقَةٌ " . قِيلَ أَرَأَيْتَ إِنْ لَمْ يَجِدْهَا قَالَ " يَعْتَمِلُ بِيَدِهِ فَيَنْفَعُ نَفْسَهُ وَيَتَصَدَّقُ " . قِيلَ أَرَأَيْتَ إِنْ لَمْ يَفْعَلْ قَالَ " يُعِينُ ذَا الْحَاجَةِ الْمَلْهُوفَ " . قِيلَ فَإِنْ لَمْ يَفْعَلْ قَالَ " يَأْمُرُ بِالْخَيْرِ " . قِيلَ أَرَأَيْتَ إِنْ لَمْ يَفْعَلْ قَالَ " يُمْسِكُ عَنِ الشَّرِّ فَإِنَّهَا صَدَقَةٌ " .
