The Prophet of Allah (Peace be upon him) said:“Every pious deed is sadaqah (charity).”
(Bukhari, Muslim, Abu Dawood, Hakim)

The Prophet of Allah,may Allah bless him and grant him peace, said: “Every Muslim must give Sadaqah.” He was asked “how should one act if he had nothing to give?” He replied: “He should work with his hands to earn for himself and give Sadaqah from it.”“The Companions asked, what if one can’t work?” The Prophet (Peace be upon him) said: “He should help one who is in need and distressed.” They asked him again: “what if one could not do it? He replied: “He should enjoin what is good and pious.” He was asked again: what if one can’t do it? He said: “He should refrain from sins and it would be regarded as Sadaqah.”
