This is a ḥasan gharīb ḥadīth from this chain of transmission.

787 - Aḥmad ibn Manīʿ narrated to us, saying: ʿAbd Allāh ibn Idrīs narrated to us, from Yazīd ibn Abī Ziyād, from Miqsam, from Ibn ʿAbbās: that the Prophet, peace and blessings be upon him, had himself cupped between Mecca and Medina while he was in a state of iḥrām and fasting.

--------------------------------------------
= (2888).

(1) Its chain is weak due to the weakness of Yazīd ibn Abī Ziyād. It was also recorded by Abū Dāwūd (2373), Ibn Mājah (1682) and (3081), and al-Nasāʾī in al-Kubrā (3226–3228), and it is in al-Musnad (1849).

Al-Ḥāfiẓ Ibn Ḥajar said in al-Talkhīṣ al-Ḥabīr 2/191, after citing the ḥadīth and raising the difficulty of the Prophet, peace and blessings be upon him, combining fasting with iḥrām—because it was not his practice to perform voluntary fasting while traveling, and he was never in iḥrām except while traveling, and he never traveled in Ramadan in the direction of iḥrām except in the campaign of the Conquest, and he was not in iḥrām at that time—I say: There is room for consideration in the first statement, for what prevents that? Perhaps he did it once to demonstrate permissibility, and sound reports are not rejected on such grounds. Then it became clear to me that some narrators combined the two matters in their mention, giving the impression that they occurred together. The more correct version is that of al-Bukhārī: "He had himself cupped while fasting, and he had himself cupped while in iḥrām." This should be understood as each one occurring in a separate situation, and there is nothing preventing this, for it is authentically established that he, peace and blessings be upon him, fasted in Ramadan while traveling, and it is in the two Ṣaḥīḥs with the wording: "None among us was fasting except the Messenger of Allāh, peace and blessings be upon him, and ʿAbd Allāh ibn Rawāḥah." This is strengthened by the fact that most of the ḥadīths are reported with this distinction.

Some of the ḥuffāẓ said: The ḥadīth of Ibn ʿAbbās is reported in four forms: first, "He had himself cupped while in iḥrām"; second, "He had himself cupped while fasting"; third, "He had himself cupped while fasting, and he had himself cupped while in iḥrām"; fourth, "He had himself cupped while fasting and in iḥrām."

The first is reported through multiple chains from Ibn ʿAbbās, and the two [Bukhārī and Muslim] agreed upon it from the ḥadīth of ʿAbd Allāh ibn Buḥaynah, and in al-Nasāʾī and others from the ḥadīth of Anas and Jābir. =
