Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Mujahid (may Allah be pleased with him) that Hazrat Abu Sufyan (may Allah be pleased with him) deceived Hazrat Hasan and Husain (may Allah be pleased with them both) regarding granting protection; both of them were young. Hazrat Sufyan said: It is not permissible for children to grant protection.
