Jami` at-Tirmidhi, Volume 4, Book 26, Hadith 2065 (DarusSalam) ⓘ
Abu Khizamah narrated from his father who said: "I asked the Messenger of Allah (S.A.W): 'O Messenger of Allah(S.A.W)! Do you think that the Ruqyah we use, the treatments we use, and what we seek to protect ourselves will contradict anything from Allah's Decree?' He said: 'They are from Allah's Decree.'"
حَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي خُزَامَةَ، عَنْ أَبِيهِ، قَالَ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقُلْتُ يَا رَسُولَ اللَّهِ أَرَأَيْتَ رُقًى نَسْتَرْقِيهَا وَدَوَاءً نَتَدَاوَى بِهِ وَتُقَاةً نَتَّقِيهَا هَلْ تَرُدُّ مِنْ قَدَرِ اللَّهِ شَيْئًا قَالَ " هِيَ مِنْ قَدَرِ اللَّهِ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
