And keep thy soul content with those who call on their Lord morning and evening, seeking His Face; and let not thine eyes pass beyond them, seeking the pomp and glitter of this Life; no obey any whose heart We have permitted to neglect the remembrance of Us, one who follows his own desires, whose case has gone beyond all bounds.
Say ye: “We believe in Allah, and the revelation given to us, and to Abraham, Isma’il, Isaac, Jacob, and the Tribes, and that given to Moses and Jesus, and that given to (all) prophets from their Lord: We make no difference between one and another of them: And we bow to Allah (in Islam=Peace).”
One who proceeds on a path in the pursuit of knowledge, God makes him proceed therewith on a path to the Garden (Paradise). And, verily, the angels spread their wings for the seekers of knowledge out of delight. Verily, every creature of the heaven and the earth asks forgiveness for the seeker of knowledge, even the fish in the sea. The merit of the ‘alim (the learned) over the ‘abid (the devout) is like the merit of the moon over the stars on a full-moon night. The learned are the heirs of the prophets, for the prophets did not leave behind a legacy of wealth but that of knowledge. So whoever partakes of it derives a plenteous benefit
Prophet Muhammad (pbuh)
