Ibn Jurayj ابن جريج · Wages (Kitab Al-Ijarah)

The Prophet (ﷺ) as saying: If anyone buys sheep whose udders have been tied up, he has option for three days: he may return it if he desires with a sa' of any grain, not (necessarily) wheat.

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.

Ibn Mas'ud sold slaves to al-Ash'ath b. Qais. He then narrated the rest of the tradition to the same effect with some variation of words.

The Messenger of Allah (ﷺ) decreed the right to buy the neighboring property applicable to everything which is not divided, but when boundaries are fixed and separate roads made, there is no option.

The life-tenancy which the Messenger of Allah (ﷺ) allowed was only that one should say: It is for you and your descendants. When he says: It is yours as long as you live, it returns to its owner.
