Sunan Abu Dawood 3855 | Authentic|

Narrated Usamah ibn Sharik: I came to the Prophet صلی ‌اللہ ‌علیہ ‌وسلم and his Companions were sitting as if they had birds on their heads. I saluted and sat down. The desert Arabs then came from here and there. They asked: Messenger of Allah, should we make use of medical treatment? He replied: Make use of medical treatment, for Allah has not made a disease without appointing a remedy for it, with the exception of one disease, namely old age.

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ النَّمَرِيُّ، ‏‏‏‏‏‏حَدَّثَنَا شُعْبَةُ، ‏‏‏‏‏‏عَنْ زِيَادِ بْنِ عِلَاقَةَ، ‏‏‏‏‏‏عَنْ أُسَامَةَ بْنِ شَرِيكٍ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ أَتَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَصْحَابَهُ كَأَنَّمَا عَلَى رُءُوسِهِمُ الطَّيْرُ، ‏‏‏‏‏‏فَسَلَّمْتُ ثُمَّ قَعَدْتُ، ‏‏‏‏‏‏فَجَاءَ الْأَعْرَابُ مِنْ هَا هُنَا وَهَهُنَا، ‏‏‏‏‏‏فَقَالُوا:‏‏‏‏ يَا رَسُولَ اللَّهِ، ‏‏‏‏‏‏أَنَتَدَاوَى ؟، ‏‏‏‏‏‏فَقَالَ:‏‏‏‏ تَدَاوَوْا، ‏‏‏‏‏‏فَإِنَّ اللَّهَ عَزَّ وَجَلَّ لَمْ يَضَعْ دَاءً إِلَّا وَضَعَ لَهُ دَوَاءً غَيْرَ دَاءٍ وَاحِدٍ الْهَرَمُ .
