The phrase (its chain of transmission is not strong) was ruled by Imam Al-Bayhaqi, may God have mercy on him, in his book Al-Sunan Al-Kubra on the hadiths. I found that this phrase, according to Imam Al-Bayhaqi, is one of the phrases that strengthens when supported and the hadith rises to the level of Hasan li ghayrihi. Some of the hadiths that he ruled with this phrase after studying the chain of transmission, it became clear that it is a Hasan chain of transmission and not weak, due to the approval of the scholars of criticism and approval of these narrators who were weakened by Imam Al-Bayhaqi, may God have mercy on him. It becomes clear to us that these hadiths are Hasan hadiths based on their chain of transmission or by the support of another chain of transmission for this hadith, if the weakness is not severe, the hadith is strengthened to the level of Hasan li ghayrihi. And God knows best.
