Anas bin Malik (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) said: "I am not of falsehood, nor is falsehood of me." This meaning was given by Abu Ubaydah.
The Shaykh says: Abu Ubayd al-Qasim bin Sallam says that "al-dad" means play and amusement.
