Sadaqah (Charity):

Referring to the charity you give voluntarily, not the obligatory Zakat. It is the voluntary sadaqah that strengthens faith, the more you do, the more you erase your bad deeds. Sadaqah is not only monetary. There are many deeds that are considered sadaqah. If someone wishes to give sadaqah, and you assist in its delivery, for example, you are rewarded for giving sadaqah yourself.

Aiesha (Radhiyallaaho T`aalaa A`nha) related that the Prophet (Ssallallaaho A`laihi Wa Aalihi Wa Sallam) informed them as to who would follow him in death saying: "The one who has the longest hands amongst you would meet me most immediately."
[Muslim]
She further said: "The Prophets wives used to measure their hands as to who was the biggest. It was the hand of Zainab that was the longest amongst them, as she used to work with her hands and spend that income in charity."
[Muslim]

It was Zainab bin Jahsh  Radhiyallaaho T`aalaa A`nha whose long hand reached out to the poor so often, not with money but food and other things that she had to give, she was the first of his wives to die after him.

The Prophet Ssallallaaho A`laihi Wa Aalihi Wa Sallam  said: "Every Muslim has to give sadaqah." He was asked "If someone has nothing to give, what should he do?" He said "He should work with his hands and benefit himself, and also give in charity (from what he earns)".
The people then asked: "If he cannot find even that?" He replied. "Then he should perform good deeds and keep away from evil deeds and this will be regarded as charitable deeds."
[Bukhari and Muslim]

He  Ssallallaaho A`laihi Wa Aalihi Wa Sallam also said: "None of you women should consider even a sheeps trotter too insignificant a gift to give to her neighbour."
[Bukhari and Muslim]

Mu'aadh bin Jabal Radhiyallaaho T`aalaa A`nho related from the Prophet  Ssallallaaho A`laihi Wa Aalihi Wa Sallam : "Sadaqah extinguishes sin as water extinguishes fire."
[Ahmad, Al-Tirmidi and Ibn Maajah]

The Prophet Ssallallaaho A`laihi Wa Aalihi Wa Sallam  said: "The believers shade on the day of resurrection will be his sadaqah."
[Ahmad]
