Salam Guys,
I would request my readers to not to mark this question as duplicate. This question is a bit different from the previous question I asked about narrator Minhal Ibn Amr.
My question is about particular narrations that come from Al-A'mash through Minhal Ibn Amr.
According to THIS source it has been stated that both Yahya ibn Ma'īn and Adh-Dhahabi had reasons to weaken narrations that came from Al-A'mash through Al-Minhāl ibn 'Amr.
The problem here is that the user III-AK-III who posted his answer did not cite any reference in order to prove that Yahya bin Ma'in and Ad-Dhahabi actually weakened the narrations that come from Al-A'mash through Minhal Ibn Amr.
Al-A'mash and Minhal were Kufi and met each other. Both of them have also narrated narrations in Bukhari.
The main question is: where is the evidence that suggests that Yahyah bin Ma'in and Ad-Dhahabi weakened the narration that come from Al-A'mash through Minhal Ibn Amr?
