What is the meaning of "Time has revolved to its original state on the day Allah created the heavens and the earth," and did the Messenger of Allah abolish the days of Nasi'?

The meaning of the Prophet's (peace and blessings be upon him) saying: "Time has revolved to its original state on the Day Allah created the heavens and the earth," is that the year in which he performed the Farewell Pilgrimage, Dhul-Hijjah arrived at its natural position. It does not mean that he abolished some days. The Prophet (peace and blessings be upon him) clarified that delaying, exchanging, or abolishing months, which the Arabs used to do in the pre-Islamic era of ignorance (Jahiliyyah), is forbidden in Islam.
