Buraida said that he heard God’s Messenger say, “A human being has three hundred and sixty joints for each of which he must give alms.” On being asked who was capable of doing that 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 <i>rak'as</i> in the forenoon will suffice you.” Abu Dawud transmitted it.

وَعَن بُرَيْدَة قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «فِي الْإِنْسَانِ ثَلَاثُمِائَةٍ وَسِتُّونَ مَفْصِلًا فَعَلَيْهِ أَنْ يَتَصَدَّقَ عَنْ كُلِّ مَفْصِلٍ مِنْهُ بِصَدَقَةٍ» قَالُوا: وَمَنْ يُطِيقُ ذَلِكَ يَا نَبِيَّ اللَّهِ؟ قَالَ: «النُّخَاعَةُ فِي الْمَسْجِدِ تَدْفِنُهَا وَالشَّيْءُ تُنَحِّيهِ عَنِ الطَّرِيقِ فَإِنْ لَمْ تَجِدْ فَرَكْعَتَا الضُّحَى تُجْزِئُكَ» . رَوَاهُ أَبُو دَاوُدَ
