عَنْ زِيَادِ بْنِ عِلَاقَةَ عَنْ أُسَامَةَ بْنِ شَرِيكٍ رَضِيَ اللَّهُ عَنْهُ رَجُلٍ مِنْ قَوْمِهِ قَالَ جَاءَ أَعْرَابِيٌّ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ يَا رَسُولَ اللَّهِ أَيُّ النَّاسِ خَيْرٌ قَالَ أَحْسَنُهُمْ خُلُقًا ثُمَّ قَالَ يَا رَسُولَ اللَّهِ أَنَتَدَاوَى قَالَ تَدَاوَوْا فَإِنَّ اللَّهَ لَمْ يُنْزِلْ دَاءً إِلَّا أَنْزَلَ لَهُ شِفَاءً عَلِمَهُ مَنْ عَلِمَهُ وَجَهِلَهُ مَنْ جَهِلَهُ
Usamah bin Sharik narrates from a man of his tribe that a Bedouin came to the Prophet Muhammad (peace and blessings be upon him) and said: O Messenger of Allah! Who among the people is the best? The Prophet (peace and blessings be upon him) replied: The one who has the best character. He then said: O Messenger of Allah! Can we seek medical treatment? The Prophet (peace and blessings be upon him) replied: Absolutely, seek treatment. Allah Almighty has not sent down any disease except that He has also created its cure and its healing; whoever knows it, knows it, and whoever remains unaware of it, remains unaware.
