What is the authenticity of the hadith regarding the song that includes: "The full moon has risen over us," and where exactly is the Farewell Bend located?

The questioner : Regarding, O Shaykh, the famous song about the arrival of the Prophet (peace and blessings be upon him) in Madinah: "The full moon has risen over us" in the biography.

The Shaykh: Yes.

The questioner : First, we want the ruling on it in terms of authenticity. The second matter is verifying the Farewell Bend; in your view, is it on the road between Makkah and Tabuk, or between Makkah and Madinah?

The Shaykh : As for the first, the hadith is not valid because it is mu'addal (missing a link in the chain). It is narrated by a man known as Ibn Abi Ayyash, who said: "Between him and the Messenger are deserts, as they say." As for the Farewell Bend, as Ibn al-Qayyim (may Allah have mercy on him) verified it, and there is no difficulty in that at all, it is for the one coming from Tabuk to Madinah, not for the one coming from Makkah. Therefore, this is another aspect showing the invalidity of this narration, and this is what some of the contemporary scholars today call internal criticism, meaning: criticism of the text.

The questioner : Some scholars interpret it as the existence of multiple bends, saying: it is permissible that there is a bend from the direction of Tabuk and a bend from the direction of Makkah.

The Shaykh : Yes, but that does not harm us or benefit us if there is another bend. However, the Messenger (peace be upon him) did not come when he was welcomed from there. Therefore, the story is not authentic, neither in its chain nor in its text.
