[Quran 21:31] And We placed within the earth firmly set mountains, lest it should shift with them, and We made therein [mountain] passes [as] roads that they might be guided.
[Quran 78:6] Have We not made the earth an expanse,
[Quran 78:7] And the mountains as pegs?
Surah Al-Anfal, Verse 24:
O you who believe!
answer (the call of) Allah and His Apostle when he calls you to that which gives you life;
and know that Allah intervenes between man and his heart,
and that to Him you shall be gathered.
Surah Al-Baqara, Verse 269:
He grants wisdom to whom He pleases,
and whoever is granted wisdom,
he indeed is given a great good and none but men of understanding mind.
