Mirza Mahmoud did not believed in Quranic verse 3:55 as prove for the death of Hazrat Eisa e.a. However Qadyani Mullahs present this verse against their own Khalifas .

Most of the Qadyanis present 3:55 as prove to show to Muslims that Jesus e.s (hazrat Eisa) e.s has died and Muslims & Christians are wrong in their beliefs that Hazrat Eisa e.s was risen to Sky.( Qadyanis use word intentionally heaven) .

إِذْ قَالَ ٱللَّهُ يَـٰعِيسَىٰٓ إِنِّى مُتَوَفِّيكَ وَرَافِعُكَ إِلَىَّ وَمُطَهِّرُكَ مِنَ ٱلَّذِينَ كَفَرُوا۟ وَجَاعِلُ ٱلَّذِينَ ٱتَّبَعُوكَ فَوْقَ ٱلَّذِينَ كَفَرُوٓا۟ إِلَىٰ يَوْمِ ٱلْقِيَـٰمَةِ ۖ ثُمَّ إِلَىَّ مَرْجِعُكُمْ فَأَحْكُمُ بَيْنَكُمْ فِيمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ

Actual Translation : Remember˺ when Allah said, “O Jesus! I will take you¹ and raise you up to Myself. I will deliver you from those who disbelieve, and elevate your followers above the disbelievers until the Day of Judgment. Then to Me you will ˹all˺ return, and I will settle all your disputes. 

However Mirza Mahmoud has clearly and expressly written that these verses donot prove the death of Jesus (esia e.s) .He says even if whole world is on one side and want to show some one as dead and God is on one side , they cannot prove . He says this verse ( 3:55) cannot prove Jesus as dead , and it is wastage of my time to argue .

Conclusion : Qadyani Mullahs versus their Own Mullahs are not on one line with each other regarding Quranic Verse 3:55
