Hadith Q1226
الَّتِي تُجْزِئُ رَكْعَتَا الضُّحَى مِنَ الصَّدَقَةِ الَّتِي عَلَى تِلْكَ الْمَفَاصِلِ كُلِّهَا
And the two rak'ahs of Duha suffice for the obligatory charity due on these joints.
Hadith 1226
Sayyiduna Buraidah (may Allah be pleased with him) narrates that I heard the Messenger of Allah (peace and blessings be upon him) saying: "There are three hundred and sixty joints in the human body. It is obligatory upon him to give charity for each joint." He (Buraidah) asked, "O Messenger of Allah, who has the ability to give so much charity?" The Prophet (peace and blessings be upon him) said: "Bury the phlegm lying in the mosque or remove something harmful from the path. If you are unable to do even this, then two rak‘ahs of Duha (forenoon) prayer will suffice for you."
