ahmad:23156Isḥāq b. Yūsuf > Sufyān > Manṣūr > Hilāl b. Yisāf > Dhakwān > a man from al-Anṣār

[Machine] The Messenger of Allah, ﷺ , once encountered a man with a wound. The Messenger of Allah, ﷺ , said, "Call upon the doctors of the Bani Fulan (a specific tribe)." So they called upon him, and he came. They asked, "O Messenger of Allah, will medication be of any benefit?" He said, "Glory be to Allah, has Allah sent down any illness upon the earth without providing a cure for it?"  

أحمد:٢٣١٥٦حَدَّثَنَا إِسْحَاقُ بْنُ يُوسُفَ حَدَّثَنَا سُفْيَانُ عَنْ مَنْصُورٍ عَنْ هِلَالِ بْنِ يِسَافٍ عَنْ ذَكْوَانَ عَنْ رَجُلٍ مِنَ الْأَنْصَارِ قَالَ

عَادَ رَسُولُ اللهِ ﷺ رَجُلًا بِهِ جُرْحٌ فَقَالَ رَسُولُ اللهِ ﷺ ادْعُوا لَهُ طَبِيبَ بَنِي فُلَانٍ قَالَ فَدَعَوْهُ فَجَاءَ فَقَالُوا يَا رَسُولَ اللهِ وَيُغْنِي الدَّوَاءُ شَيْئًا؟ فَقَالَ سُبْحَانَ اللهِ وَهَلْ أَنْزَلَ اللهُ مِنْ دَاءٍ فِي الْأَرْضِ إِلَّا جَعَلَ لَهُ شِفَاءً
