There is great reward for those people who travel in the path of Allah (SWT) to seek the knowledge and assistance. Once there was a man who travelled lots of miles just to seek the knowledge and there was no other specific purpose to make travel in his mind. After inquiring he just posed the total intention of his heart that he has come to seek the knowledge of the Holy Prophet (PBUH). And the explanation of Hadith mentions the details of explanations that whoever travel to seek the knowledge then he will be awarded with the great blessings and the angels on the earth and on the heavens will pray for him for his forgiveness.
