The allegation is that Ahmad(as) was revealed to that:
Whatever matter You determine, it takes place immediately with Your command (Ruhani Khazain Volume 22, page 108)
Non Ahmadi’s try saying this means Hazrat Mirza Ghulam Ahmad(as) thinks everything works through him and that he is God sadly. But if they had knowledge of the Quran they would understand that the Quran has states in Chapter 40 verse 61 that:
And your Lord says: ‘Pray unto Me; I will answer your prayer. But those who are too proud to worship Me will surely enter Hell, despised.’(Chapter 40 Verse 61)
This is what the revelation is telling Hazrat Mirza Ghulam Ahmad(as) , nothing more nothing less. Instead of raising this allegation the Non Ahmadi Muslims should read the Quran first and understand the meaning of answering prayer. According to them, this verse makes everyone a god which is totally ridiculous.
