Sulaiman bin Da'ud bin Da'ud سليمان بن داود بن داود بن علي · Wages (Kitab Al-Ijarah)

The Prophet (ﷺ) said: If anyone makes two transactions combined in one bargain, he should have the lesser of the two or it will involve usury.

In the time of the Messenger of Allah (ﷺ) a man suffered loss affecting fruits he had bought and owed a large debt, so the Messenger of Allah (ﷺ) said: Give him sadaqah (alms). So the people gave him sadaqah (alms), but as that was not enough to pay the debt in full, the Messenger of Allah (ﷺ) said: Take what you find. But that is all you may have.

The Messenger of Allah (ﷺ) as saying: If you were to sell dried dates to your brother and they were smitten by blight, it will not be allowable for you to take your brother's property unjustly.

Blight means anything which obviously damages (the crop), by rain, hail, locust, blast of wind, or fire.

The Prophet (ﷺ) said: If a man sells (his) property and the man who buys it becomes insolvent, and the seller does not receive the price of the property he had sold, but finds his very property with him (i.e. the buyer), he is more entitled to it (than others). If the buyer dies, then the owner of the property is equal to the creditors.

The Prophet (ﷺ) said: It is not lawful for a man to make a donation or give a gift and then take it back, except a father regarding what he gives his child. One who gives a gift and then takes it back is like a dog which eats and vomits when it is full, then returns to its vomit.
