It paves the way to paradise

 The Messenger of Allah(PBUH) said: “Who takes a path upon which he seeks knowledge, then Allah makes a path to Paradise easy for him. And indeed the angels lower their wings in approval to the one seeking knowledge. Indeed forgiveness is sought for the knowledgeable one by whomever is in the heavens and whomever is in the earth, even the fish in the waters. " -Sahih Muslim 2699
