Sayyiduna Iyad bin Himar Mujashi’i (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said in a sermon:“Indeed, Allah Almighty has commanded me to teach you those matters of which you are ignorant, from among the matters which He has taught me today. And He has also said that every thing which I have bestowed upon My servants is lawful for them.”
