"its chain is authentic." It has a corroborating narration from Anas similar to the narration of al-Nasāʾī, recorded by Ibn al-Ḍuraysī in "Aḥādīth Muslim ibn Ibrāhīm al-Azdī" (5/1) with a chain whose narrators are trustworthy.

However, the ḥāfiẓ refuted it in "al-Fatḥ" and mentioned that it refers to the yellow one, supporting this with the upcoming ḥadīth, and the response to it will be given therein. It is:
