A person has to (direct) his intention to Allaah in seeking knowledge-being sincere to Allaah and neither desiring (سمعة i.e. his intention should not be the desire to be heard) nor (رياء i.e. his intention should not be the desire to be seen); neither seeking fame nor a worldly goal from the worldly goals. Whoever directs his intention (sincerely) to Allaah, then Allaah will grant him success and reward him based on that. That is because (seeking) knowledge is worship; rather it is from the greatest (affairs of worship).
