In his book “Wasailu  shia” this shia scholar said:

ومثله يأتي في رواية الثقات ؛ الأجلاء ـ كأصحاب الإجماع ، ونحوهم ـ عن الضعفاء ، والكذابين ، والمجاهيل ، حيث يعلمون حالهم ، ويروون عنهم ، ويعملون بحديثهم ، ويشهدون بصحته .

“And example of this coming in the narrations of trustworthy and esteemed – like companions of ijma and (others) like them – from weak, liars, and unknown (narrators), when their knew their conditions, and narrated from them, and they knew their narrations, and testified their authenticy”.
