Giving voluntary charity is sunna, and in places afflicted with drought and famine it becomes a confirmed sunna for water and milking goats

(A milker goat lent by one to his neighbor (o make use of her milk, so long as it has milk).

It is to give away in charity anything that is in excess of one's needs, provided one can bear the results.

Abu Sa'id Al-Khadari (G. p. H) said: "The Messenger of Allah (P. B. U. H) said:

"'If any of you has an extra riding animal, let him give it to one who does not, and if any of you has extra food, let him give it to one who does not. '

Until we thought that we had no right in possessing anything that is extra".

[Abu Dawood, Vol. 2, The Book of zakat, Chapter 32/1663].

It is makrooh for one to get back his charity from he whom he donated it to by means of purchase.

(Such as donating an amount of wheat then asking the one who look the charity to sell him the wheat he was given).

It is forbidden to give away in charity what one needs to sustain oneself and his dependants for that particular day and night with, or what one needs to pay back a debt with.

Asking for money is forbidden for anyone who is self-sufficient by wealth or by income, for Sahl ibn Al-Hanzalia (G. p. H) said: "The Messenger of Allah (P. B. U. H) said:

"Whoever asks for money while he has what suffices him, he is demanding the embers of Hell".

It was said: '0 Messenger of Allah, what is sufficient for one?"

He said: "As much as is necessary for his lunch or dinner".
