As Salamu Alaykum Is it permissible to listen to the poetry of Abū al-Ṭayyib Aḥmad ibn al-Ḥusayn al-Mutanabbī ? A student of knowledge mentioned to me that scholars debate whether he was a kaffir but L1 in Thalathatul Usool it was mentioned that Shaykh Salih Al As-Shaykh (hafidhahullah) quotes him

Ustadh AbdulAziz al-Haqqan

When the ulama quote that which is beneficial then u can benefit, but don't waste your time on love poetry and nonesense like that.
