Muslim narrated on the authority of Abu Hurairah, who said that the Messenger of God, may God’s prayers and peace be upon him, addressed us and said, “O people, God has imposed Hajj on you, so they performed Hajj.” A man said, “Every year, O Messenger of God.” He was silent until he said it three times, so the Messenger of God, may God’s prayers and peace be upon him, said, “If only I said, “Yes, if it is obligatory, and if you are able,” then he said, “Leave me as long as I have left you, for those who were before you perished because of their abundance of questioning and disagreement with their prophets. If I command you to do something, do as much of it as you can, and if I forbid you to do something, abandon it.

Al-Nasa’i said from the hadith of Ibn Abbas. If I had said yes, it would have been obligatory, and then you would not listen or obey, but it is one proof.
