Narrated Abu Buraydah:I heard the Messenger of Allah (ﷺ) say: A human being has three hundred and sixty joints for each of which he must give alms. The people asked him: Who is capable of doing this ? He replied: It may be mucus in the mosque which you bury, and something which you remove from the road; but if you do not find such, two rak'ahs in the forenoon will be sufficient for you.
حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ الْمَرْوَزِيُّ، قَالَ حَدَّثَنِي عَلِيُّ بْنُ حُسَيْنٍ، حَدَّثَنِي أَبِي قَالَ، حَدَّثَنِي عَبْدُ اللَّهِ بْنُ بُرَيْدَةَ، قَالَ سَمِعْتُ أَبِي بُرَيْدَةَ، يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " فِي الإِنْسَانِ ثَلاَثُمِائَةٍ وَسِتُّونَ مَفْصِلاً فَعَلَيْهِ أَنْ يَتَصَدَّقَ عَنْ كُلِّ مَفْصِلٍ مِنْهُ بِصَدَقَةٍ " . قَالُوا وَمَنْ يُطِيقُ ذَلِكَ يَا نَبِيَّ اللَّهِ قَالَ " النُّخَاعَةُ فِي الْمَسْجِدِ تَدْفِنُهَا وَالشَّىْءُ تُنَحِّيهِ عَنِ الطَّرِيقِ فَإِنْ لَمْ تَجِدْ فَرَكْعَتَا الضُّحَى تُجْزِئُكَ " .
