I can give you reasons why I believe that there is the Creator. I cannot give you tangible proof for the existence of God. I can give you reason.
And if it’s a good reason then that’s a belief. We as Muslims, we’re not taught just to believe in God blindly.
In fact, if you read the Quran, it’s so intellectual, it challenges the reader.
Do they not consider the Qur’an (with care)? Had it been from other Than Allah, they would surely have found therein Much discrepancy. SURAH AN-NISA AYAT 82 (4:82 QURAN)
The Quran is actually opening for you to challenge. If you don’t believe this is from God, if you don’t believe this from Allah, prove it wrong.
