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. (Using translation from Abū Dāʾūd 5242)
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ فِي الْإِنْسَانِ سِتُّونَ وَثَلَاثُ مِائَةِ مَفْصِلٍ فَعَلَيْهِ أَنْ يَتَصَدَّقَ عَنْ كُلِّ مَفْصِلٍ مِنْهَا صَدَقَةً قَالُوا فَمَنِ الَّذِي يُطِيقُ ذَلِكَ يَا رَسُولَ اللهِ؟ قَالَ النُّخَاعَةُ فِي الْمَسْجِدِ تَدْفِنُهَا أَوِ الشَّيْءُ تُنَحِّيهِ عَنِ الطَّرِيقِ فَإِنْ لَمْ تَقْدِرْ فَرَكْعَتَا الضُّحَى تُجْزِئُ عَنْكَ
