the high status of knowledge has been established very strongly in Islam through explicit texts in the Qu'ran and Hadith, as well as in the writings of many scholars in Islam
Allah said in the Qu'ran that He raises the rank of those among you who believe and were granted the knowledge
Also Allah said in the Qur'an those who know are not equal to those who do not know
Also Allah said in the Qur'an those who have the knowledge fear Allah the most
Moreover, Allah revealed to Prophet Muhammad to praise the status of knowledge, it's teachers, and it's students
The Prophet(may Allah raise his rank) said 'O Abu Dahr(one of the companions), if you go and learn one verse of the Qur'an it will be more rewardable for you than praying 100 Rakkaths of the optional prayer, and if you go and learn one chapter of the obligatory knowledge it will be more rewardable for you than praying 1,000 Rakkaths of the optional prayer
Imam Ali Abu Talib the fourth Caliph said knowledge is better than money, because knowledge protects you whereas you protect money
knowledge rules over things whereas money is ruled over
money diminishes as you spend it, whereas spending the knowledge by teaching it to others increases your reward
