AsSalamu ‘Alaykum

There is a narration which is ‘Ali رضي الله عنه permitting a marriage of a woman without her father giving consent nd giving her mother permission to give consent instead. However, after further research on this narration I have found the complete Isnaad for it in Musannaf ibn abi shaybah:

حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الشَّيْبَانِيِّ، عَنْ أَبِي قَيْسٍ الْأَوْدِيِّ، *عَمَّنْ حَدَّثَهُ*، عَنْ عَلِيٍّ، أَنَّهُ «أَجَازَ نِكَاحَ امْرَأَةٍ بِغَيْرِ وَلِيٍّ، أَنْكَحَتْهَا أُمُّهَا بِرِضَاهَا»

In the bold is where I am getting skeptical, because from the apparent this is a Majhool narrator whom Abi Qays narrates from. I don’t know who it could be though, but iirc Abi Qays doesn’t usually narrate from weak people although I could be wrong.

Please help me with the grading of this narration, JazakAllahu khairun
