Questioning is Half of Knowledge...

~ The Prophet Muhammad (peace be upon him) said: "The seeking of knowledge is obligatory for every Muslim."

Al-Tirmidhi, Hadith 74

~ The Prophet Muhammad (peace be upon him) said: "God, His angels and all those in Heavens and on Earth, even ants in their hills and fish in the water, call down blessings on those who instruct others in beneficial knowledge." 

Al-Tirmidhi, Hadith 422

~ The Prophet also said: "Knowledge from which no benefit is derived is like a treasure out of which nothing is spent in the cause of God."

Al-Tirmidhi, Hadith 108
