Khwaja Anwar and Mukesh saheb, Assalam o alaikum,
The word apostasy is for the one who is FASIQ, the one who destroyed allegiance in the light of verse 48:10 for the 49th Imam and Fatemi Khalifatullah of our age for the obedience of prophet Mohammad SUH and HP and Allahussamad in the light of verse 4:59. If you are the one engaged in KHUDPARASTI, then you would certainly agree to this. Dr. Zakir Naik like you in not pledged to 49th Imam and Fatemi Khalifatullah, the MUSLIM, the one and only one. Therefore, he can not be called an apostate. The apostates of our age include Gulshan Aalani, Qasim Ali Ismail etc.who reneged from allegiance to 49th Imam and Fatemi Khalifatullahs. Such are PAKHANDHIES who did not follow the leg of divinely chosen.
