But those of them with well-founded knowledge who are acquainted with the facts, whose hearts have been touched with the divine hand, are they who give credence to all that has been revealed to you Muhammad and to all that was revealed to those who were sent before you; they constantly observe their act of worship and give alms, they believe in Allah and in the Day of Resurrection with hearts impressed with the image of religious and spiritual virtues. It is those whom We shall requite with a great reward.
