The Qur’an is the word of Allah Almighty. It was revealed to our Prophet Muhammad (peace and blessings of Allah be upon him) by Jibreel (peace be upon him).
The evidence for this is:
1- If it were the word of a human and they were revealed during a span of 23 years, there would be many differences and contradictions in it. When a person grows up, his style changes and his thoughts change, so how is it that the Qur’an’s style at the beginning of the revelation did not change from its style after many years?
2- The Qur’an came more than 1400 years ago and has covered many topics in science, astronomy, and medicine, and these topics and sciences were not known in the days of the Prophet, may Allah bless him and grant him peace. Modern science is still discovering many things in the Qur’an.
3- Allah Almighty challenged the polytheists to come up with a surah like the Qur’an, but when they did not, He challenged them to with a verse, but they still could not.
( Do they not then reflect on the Quran? Had it been from anyone other than Allah, they would have certainly found in it many inconsistencies.) An-Nisa 4: 82
( Say, ˹O Prophet,˺ “If ˹all˺ humans and jinn were to come together to produce the equivalent of this Quran, they could not produce its equal, no matter how they supported each other.”) Al-Isra’a 17:88
القرآن هو كلام الله تعالى. و قد أنزله على نبينا محمد صلى الله عليه و سلم بواسطة جبريل عليه السلام.
و الدليل على ذلك
أنه لوكان كلام بشر و قد نزل خلال 23 سنة لكان فيه اختلافات و تناقدات كثيرة. فالإنسان عندما يكبر يتغير أسلوبه و يتغير فكره فكيف هذا القرآن تجد الأسلوب في أول نزوله لم يتغير عن أسلوبه بعد أعوام كثيرة.
جاء القرآن منذ أكثر من 1400 سنة و قد تطرق لموضيع كثيرة في العلم و الفلك, و الطب ولم تكن معروفة هذه المواضيع و العلوم بأيام الرسول صلى الله عليه و سلم. و لا يزال العلم الحديث إلى عامنا هذا يكتشف أمور كثيرة جاءت في القرآن.
الله تعالى تحدى المشركين بأن يأتوا بسورة مثل القرآن فلم يستطيعوا فتحداهم أن يأتوا بآية فلم يستطيعوا.
(أَفَلَا يَتَدَبَّرُونَ الْقُرْآنَ ۚ وَلَوْ كَانَ مِنْ عِندِ غَيْرِ اللَّـهِ لَوَجَدُوا فِيهِ اخْتِلَافًا كَثِيرًا ﴿٨٢﴾ النساء 4: 82
قُل لَّئِنِ اجْتَمَعَتِ الْإِنسُ وَالْجِنُّ عَلَىٰ أَن يَأْتُوا بِمِثْلِ هَٰذَا الْقُرْآنِ لَا يَأْتُونَ بِمِثْلِهِ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍ ظَهِيرًا ) الإسراء 17: 88
