Al-An'am 6:41
بَلْ إِيَّاهُ تَدْعُونَ فَيَكْشِفُ مَا تَدْعُونَ إِلَيْهِ إِن شَآءَ وَتَنسَوْنَ مَا تُشْرِكُونَ
Bal iyyahu tadAAoona fayakshifu matadAAoona ilayhi in shaa watansawna ma tushrikoon
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].
Rather, Him alone you will call and He, if He wills, shall remove what you call Him for, and you will forget those you associate with Him.
