You said “AS A PROVE OF JUDGEMENT DAY” but there are many other ways to prove that. Killing someone just because he is not accepting what you are preaching doesn’t make sense. When there is day of judgement then punishment for disbelievers in this world seems illogical. Okay let’s just accept that they didn’t believe even after knowing the truth the God should have killed them by natural phenomenas because that would have made sense but Prophet Muḥammad ﷺ killed them and said it was from God. My mind is not ready to accept that. When God in the past had destroyed people by natural disasters then GOD should have done it by himself.
