وَمَا قَدَرُوا۟ ٱللَّهَ حَقَّ قَدْرِهِۦٓ إِذْ قَالُوا۟ مَآ أَنزَلَ ٱللَّهُ عَلَىٰ بَشَرٍۢ مِّن شَىْءٍۢ ۗ قُلْ مَنْ أَنزَلَ ٱلْكِتَٰبَ ٱلَّذِى جَآءَ بِهِۦ مُوسَىٰ نُورًۭا وَهُدًۭى لِّلنَّاسِ ۖ تَجْعَلُونَهُۥ قَرَاطِيسَ تُبْدُونَهَا وَتُخْفُونَ كَثِيرًۭا ۖ وَعُلِّمْتُم مَّا لَمْ تَعْلَمُوٓا۟ أَنتُمْ وَلَآ ءَابَآؤُكُمْ ۖ قُلِ ٱللَّهُ ۖ ثُمَّ ذَرْهُمْ فِى خَوْضِهِمْ يَلْعَبُونَ
And they measure not the power of Allah its true measure when they say: Allah hath naught revealed unto a human being. Say (unto the Jews who speak thus): Who revealed the Book which Moses brought, a light and guidance for mankind, which ye have put on parchments which ye show, but ye hide much (thereof), and (by which) ye were taught that which ye knew not yourselves nor (did) your fathers (know it)? Say: Allah. Then leave them to their play of cavilling.

Chapter: The Ruqya of the Prophet (saws)
Narrated `Aisha:
The Prophet (ﷺ) used to treat some of his wives by passing his right hand over the place of ailment and used to say, "O Allah, the Lord of the people! Remove the trouble and heal the patient, for You are the Healer. No healing is of any avail but Yours; healing that will leave behind no ailment."
