May Allah disgrace Khomayni in both of the worlds!
In his book “Kashful asrar” (p 143) he wrote that Abul Abbas ibn Uqda wrote the book about chains of hadith al-Qadir. And as you can see Khomayni claimed that ibn Uqda was from prominent sunnis!
But imam Dhahabi said in Mizanul itidal (1/136) about this ibn Uqda:
شيعي متوسط. ضعفه غير واحد، وقواه آخرون.
Average shia, was weakened by more than one (scholar) and strengthen by others.
