It will be a day when no one can help another. It will be a day when no amount of money can help you. You must have been a trillionaire. You must have been the the CEO of fusion technologies Microsoft corporation, earned billions on a monthly basis. I mean can you get any richer than this. The answer is no. But on judgement day if you were not a muslim then your trillions are useless and you will be utterly and completely helpless in the presence of the one and only creator (Allah subhana wa tha alaa).
It will be a day so terrifying , imagine the worst horror film you have seen and times (x) by a billion trillion that is how much that day, the day in the future, the day of judgement, that is how terrifying and scary it will be, to those who ignored islam. To those who mocked Muhammad (peace be upon him). DON'T SAY I DID NOT WARN YOU !
