كَمَآ أَرْسَلْنَا فِيكُمْ رَسُولًۭا مِّنكُمْ يَتْلُوا۟ عَلَيْكُمْ ءَايَٰتِنَا وَيُزَكِّيكُمْ وَيُعَلِّمُكُمُ ٱلْكِتَٰبَ وَٱلْحِكْمَةَ وَيُعَلِّمُكُم مَّا لَمْ تَكُونُوا۟ تَعْلَمُونَ
Even as We have sent unto you a messenger from among you, who reciteth unto you Our revelations and causeth you to grow, and teacheth you the Scripture and wisdom, and teacheth you that which ye knew not.
