[2:269] He [Allah] grants wisdom to whom He pleases; and he to whom wisdom is granted indeed receives a benefit overflowing. But none will grasp the Message except men of understanding.
[20:114] High above all is Allah, the King, the Truth. Do not be in haste with the Qur'an before its revelation to you is completed, but say, "O my Sustainer! Increase my knowledge."
[3:190-191] Verily in the creation of the heavens and the earth, and the alternation of night and day - there are indeed signs for men of understanding; Men who remember Allah, standing, sitting, and lying down on their sides, and contemplate the creation of the heavens and the earth (with the thought) "Our Lord! Not for nothing have You created (all) this. Glory to You! Give us salvation from the suffering of the Fire."
[39:9] ...Say: Are those equal, those who know and those who do not know? It is those who are endued with understanding that remember (Allah's Message).
[58:11] ...Allah will raise up to (suitable) ranks (and degrees) those of you who believe and who have been granted knowledge.
