“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)
أَنَّهُ قَالَ يَا رَسُولَ اللهِ رُقًى كُنَّا نَسْتَرْقِي بِهَا وَأَدْوِيَةٌ كُنَّا نَتَدَاوَى بِهَا هَلْ تَرُدُّ مِنْ قَدَرِ اللهِ شَيْئًا؟ قَالَ «هِيَ مِنْ قَدَرِ اللهِ ﷻ»
