Tafsir of Al-Anbiya' 21:45

قل إنما أنذركم بالوحي

Say: "I warn you only by the revelation.'' meaning, `I only convey to you the warning of Allah's punishment and vengeance, and this is no more than that which Allah reveals to me.' But this is of no benefit to the one whom Allah has made blind and has put a seal over his hearing and his heart. He says:

وﻻ يسمع الصم الدعاء إذا ما ينذرون

But the deaf will not hear the call, (even) when they are warned. Allah says:

ولين مستهم نفحة من عذاب ربك ليقولن يا ويلنا إنا كنا ظالمين
