Every day, our joints have an obligation to give sadaqah as a realization of our gratitude to Allah, the One who created we. The methods vary as mentioned by Rasulullah SAW
“Every human joint is obliged to give sadaqah every day since sunrise. Separating (solving a case) between two people who are in dispute is shadaqah. Helping someone get into his vehicle or lift his belongings onto his vehicle is shadaqah. Good words also include shadaqah. Likewise, every step of the way to perform prayer is shadaqah. And removing an obstacle from the path is sadaqah” (Narrated by Bukhari and Muslim)
So hard and tired we are if we have to do these various charities every day. So that the companions asked, “Who is capable of doing it, O Messenger of Allah?” So he replied, “If he is incapable, then two cycles of Dhuha are sufficient.” (HR Ahmad Abu Dawud)
Rasulullah SAW made it easy for his people, that all the prayers performed by the members of the body could be replaced with two cycles of Dhuha prayer, because prayer is the practice of all members of the body. If someone is praying, then each member of the body performs its respective function.
