Musannaf Ibn Abi Shaybah

Hazrat Zuhri says that if a man gave one hundred dinars in charity to his son, and both were partners and the wealth was in front of the son, then this charity is not valid until he takes possession of it. The decision of Hazrat Abu Bakr and Hazrat Umar (may Allah be pleased with them) is that if he did not take possession, he will not receive anything.
