Surah Al-An'am 6:41

بَلْ إِيَّاهُ تَدْعُونَ فَيَكْشِفُ مَا تَدْعُونَ إِلَيْهِ إِن شَآءَ وَتَنسَوْنَ مَا تُشْرِكُونَ

No, it is Him [alone] you would invoke, and He would remove that for which you invoked Him if He willed, and you would forget what you associate [with Him].

Translation: Saheeh International

Tafsir

Nay; upon Him and upon none other you will call in times of tribulation and He will remove that which you call upon Him to remove from you such things as suffering if He wills to remove it and you will forget you will neglect what you associate with Him of idols and will not call them.
