How you will believe?. What kind of sign you want for believe?. Do you want to see the hell and heaven with your own eye's?. Do you want that the mountains will turn into Gold?. You want a camel came from the mountain and then birth a baby at the same time?. Do you want that stones will talk with you?. What kind of sign you think that after that sign you will not ask any further question and become believer. Do you want that dead will alive?. What you want?. Do you ever realized what kind of thing you really want to become a believer?. Do you ever ask this question from your own self that what you want to become a believer?.
Allah in the following verse of the Holy Quran clearly mentioned that these people will never believe if you will gave them every sign they wish. The nations before them ask the same question and demand different kind of signs from the apostles of Allah; Allah send the same sign but the disbeliever refused that sign and said that it was magic and they did not become believer. The disbeliever always argument in the answer of every demanding sign that it was a magic. It is the rule of Allah that after sending the demanding sign if the nation refuse to become believer then Allah send His wrath on that nation and destroy the whole nation. Allah informed us that the disbelievers and those who have the Book Jews and Christian never follow your Book, your apostle and off course your qiblah. Neither you will believe in their qiblah so if you will change your believe after the clear orders of the Book which is revealed on your apostle then surely you will be the same going to hell.
Kindly read the following verse of the Holy Quran as mentioned below:
"And even if you bring to those who have been given the Book every sign they would not follow your qiblah, nor can you be a follower of their qiblah, neither are they the followers of each other's qiblah, and if you follow their desires after the knowledge that has come to you, then you shall most surely be among the unjust."
(Surah No: 2 & Verse No: 145)
May Allah forgive us and gave the wisdom to the disbeliever that they will believe. Only Allah can do this but according to His law He will not gave them the knowledge of His Book.
