in Edition Clear Qur'an by Talal Itani / Al-Israa (The Night Journey)
17:44Praising Him are the seven heavens, and the earth, and everyone in them. There is not a thing that does not glorify Him with praise, but you do not understand their praises. He is indeed Forbearing and Forgiving.
17:46And We drape veils over their hearts, preventing them from understanding it, and heaviness in their ears. And when you mention your Lord alone in the Quran, they turn their backs in aversion.
