Is the Hadith about "the prophet sucking on the tongue" true?

The hadith regarding the Prophet Muhammad ﷺ sucking on the tongue is mentioned in Sunan Abu Dawud, where it states: The Prophet (peace be upon him) used to kiss me while fasting and lick my tongue. Sunan Abu Dawud 14:74SunniDaif (per Al-Albani).

However, this narration is graded as Daif (weak) by scholars, which means it isn't considered a reliable source of Islamic law or practice. When evaluating hadith, scholars often prefer stronger narratives, especially for practices related to fasting and worship. Thus, while this hadith exists, its weakness impacts its credibility in establishing normative teachings about the Prophet's actions during fasting.
