حَدَّثَنَا يَحْيَى بْنُ سُلَيْمَانَ ، قَالَ : حَدَّثَنِي ابْنُ وَهْبٍ ، قَالَ : أَخْبَرَنِي عَمْرُو بْنُ الْحَارِثِ ، عَنْ دَرَّاجٍ ، أَنَّ أَبَا الْهَيْثَمَ حَدَّثَهُ ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : ”أَيُّمَا رَجُلٌ مُسْلِمٌ لَمْ يَكُنْ عِنْدَهُ صَدَقَةٌ ، فَلْيَقُلْ فِي دُعَائِهِ : اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ ، عَبْدِكَ وَرَسُولِكَ ، وَصَلِّ عَلَى الْمُؤْمِنِينَ وَالْمُؤْمِنَاتِ ، وَالْمُسْلِمِينَ وَالْمُسْلِمَاتِ ، فَإِنَّهَا لَهُ زَكَاةٌ.“
It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "If a Muslim man has nothing to give in charity, then he should say in his supplication: O Allah, send mercy upon Muhammad (peace be upon him), Your servant and Messenger, and upon the believing men and believing women, and also send mercy upon the Muslim men and Muslim women. This will be his charity."
