Go ahead with the remembrance of Allah for it is the best remembrance, and long for that which He has promised to the pious, for His promise is the most true promise. Tread the course of the Prophet for it is the most distinguished course. Follow the sunnah of the Prophet for it is the most right of all behaviours. Learn the Qur'an for it is the fairest of discourses and understand it thoroughly for it is the best blossoming of hearts. Seek cure with its light for it is the cure for hearts. Recite it beautifully for it is the most beautiful narration. Certainly, a scholar who acts not according to his knowledge is like the off-headed ignorant who does not find relief from his ignorance, but on the learned the plea of Allah is greater and grief more incumbent, and he is more blameworthy before Allah.
