My patron ordered me to cut some meat in strips and spread it in the sun to dry, and when a poor man came to me I gave him some of it to eat. My patron got to know of that and beat me, so I went to God’s messenger and mentioned the matter to him. He summoned him and asked, “Why did you beat him?” He replied, “He gives away my food without instruction from me.” Then he said, “The reward is shared between you.”
In a version he said: I was a slave and I asked God’s messenger whether I could give any sadaqa from my patron’s property. He replied, “Yes, and the reward will be shared equally between you.”
Narrated Sa'd said that when God’s messenger took the oath of allegiance from the women, a woman of high rank who seemed to be one of the women of Mudar rose and said, “Prophet of God, we are dependent* on our parents, our sons and our husbands, so with what part of their property can we do what we like?” He:
I provided a man with a horse to ride in God’s path, but as the one who had it did not look after it well, I wanted to buy it and thought he would sell it at a cheap price. I therefore asked the Prophet, but he said,
“Do not buy it, and do not take back what you gave as sadaqa even if he gives it to you for a dirham, for the one who takes back what he gave as sadaqa is like a dog which returns to its vomit.”
A version has, “Do not take back what you gave as sadaqa, for the one who does so is like one who takes back what he has vomited.”
Buraida said that when he was sitting with the Prophet a woman came to him and said, “Messenger of God, I gave a slavegirl as sadaqa to my mother who has now died.”
He replied. “Your reward is sure, and the inheritance has given her back to you.”
She said, "Messenger of God, a month's fast was due from her; may I fast on her behalf ?” He replied, “Fast on her behalf.”
She said, “She never performed the pilgrimage, so may I do so on her behalf ?” He replied, “Yes, perform the pilgrimage on her behalf.”
