“The Messenger of Allah ﷺ was asked: ‘Do you think that the medicines with which we treat ourselves, the Ruqyah by which we seek healing, and the means of protection that we seek, change the decree of Allah at all?’ He said: ‘They are part of the decree of Allah.’” (Using translation from Ibn Mājah 3437)
قُلْتُ يَا رَسُولَ اللَّهِ أَرَأَيْتَ أَدْوِيَةً نَتَدَاوَى بِهَا وَرُقًى نَسْتَرْقِي بِهَا أَتَرُدُّ مِنْ قَدَرِ اللَّهِ؟ قَالَ «إِنَّهَا مِنْ قَدَرِ اللَّهِ»
