Musannaf Ibn Abi Shaybah

Hazrat Abdul Malik bin Iyas narrates that Hazrat Amir and Ibrahim were gathered at one place. They were asked: If a person demands goods from another, and the goods are not with him, can he make a deal with him and then procure those goods? Ibrahim considered this matter to be disliked, while Hazrat Amir said that there is no harm in it; if he wishes to abandon the deal later, he may do so.
