““How many nights have you remained awake repeating science and poring over books, and have denied yourself sleep. I do not know what the purpose of it was. If it was attaining worldly ends and securing its vanities, and acquiring its dignities, and surpassing your contemporaries, and such like, woe to you and again woe; but if your purpose in it was the vitalizing of the Law of the Prophet, and the training of your character, and breaking the soul commanding to evil, then blessed are you and again blessed.””
