Its known that there is an issue of dispute whether wiping the ears during wudu is sunnah or not but why does this dispute exist when there’s an ijma existing? قال أبو جعفر محمد بن جرير الطبري في كتابه اختلاف الفقهاء أجمعوا أن من ترك مسحهما فطهارته صحيحة https://shamela.ws/book/2186/415 Jazakallah

Not every ijma' is true sometimes mistakes happen, or in thr knowledge of 1 scholar he knows of no pther opinion while there is. So maybe u have to look carefully as I am not aware of the details now.
