Amir al-Sha'bi عامر الشعبي · Wages (Kitab Al-Ijarah)

This tradition has also been transmitted by Abu Sa'id al-Khudri form the Prophet (ﷺ).

On his father's authority, said that his grandfather 'Abd Allah b. 'Amr reported the Messenger of Allah (ﷺ) as saying: The proviso of a loan combined with a sale is not allowable, nor two conditions relating to one transaction, nor profit arising from something which is not in one's charge, nor selling what is not in your possession.

We came to AbuHurayrah who had become insolvent. He said: I shall decide between you on the basis of the decision of the Messenger of Allah (ﷺ): If anyone becomes insolvent or dies and the man (the seller) finds his very property with him, he is more entitled to it (than others).

The Prophet (ﷺ) said: If anyone leaves an animal at a place of perishing and another man brings it to life, it belongs to him who brings it to life.
