All our our problems starts due go ignorance either in our physical world and needs or spiritual needs. The very first this Allah (swt) taught Prophet Adam (a.s) was Names (Asma), first Ayah revealed to Prophet (saww) says Iqra… read with the name of your Lord who has created ….
Quran says in Surah Zumar:

أَمَّنْ هُوَ قَانِتٌ آنَاءَ اللَّيْلِ سَاجِدًا وَقَائِمًا يَحْذَرُ الْآخِرَةَ وَيَرْجُو رَحْمَةَ رَبِّهِ قُلْ هَلْ يَسْتَوِي الَّذِينَ يَعْلَمُونَ وَالَّذِينَ لَا يَعْلَمُونَ إِنَّمَا يَتَذَكَّرُ أُولُو الْأَلْبَابِ

What! he who is obedient during hours of the night, prostrating himself and standing, takes care of the hereafter and hopes for the mercy of his Lord! Say: Are those who know and those who do not know alike? Only the men of understanding are mindful.(39:9)

Holy Prophet (saww) has said
Seek knowledge while you might travel China.
But unfortunately we Muslims left that main teachings of Islam and today after having all resources we most of the Muslim countries are puppets of few western countries. All these examples are enough to understand the importance of Knowledge.

How one can deny the importance of knowledge. Write now the phone im using and same time we are in 180 degree opposite direction but because of Knowledge we can communicate with each other. Knowledge is life, how can we deny it? Our beloved book Holy Quran is the best example of Knowledge.
Holy Quran says:

إِنَّمَا يَخْشَى اللَّهَ مِنْ عِبَادِهِ الْعُلَمَاءُ
‏“Those of His servants only who are possessed of knowledge fear Allah.(35:28)
