I was with him when a party of the Quraysh came to him and said to him, “O Muḥammad, you have made a big claim which none of your fore-fathers or those of your family have made. We ask you one thing; if you give us an answer to it and show it to us, we will believe that you are a prophet and a messenger, but if you cannot do it, we will know that you are a sorcerer and a liar.”
