عن أسامة بن شريك قال شهدت الأعراب يسألون النبي صلى الله عليه وسلم أعلينا حرج في كذا أعلينا حرج في كذا فقال لهم عباد الله وضع الله الحرج إلا من اقترض من عرض أخيه شيئا فذاك الذي حرج فقالوا يا رسول الله هل علينا جناح أن لا نتداوى قال تداووا عباد الله فإن الله سبحانه لم يضع داء إلا وضع معه شفاء إلا الهرم قالوا يا رسول الله ما خير ما أعطي العبد قال خلق حسن ( سنن ابن ماجة #3427 )

Hazrat Usaamah bin Shareek (radhiyallahu ‘anhu) narrates that he once witnessed some of the Bedouin asking Rasulullah (sallallahu ‘alaihi wasallam), “Is there any problem in us doing such-and-such an action? Is there any problem in us doing such-and-such an action?”Rasulullah (sallallahu ‘alaihi wasallam) replied, “O servants of Allah! Allah Ta‘ala has permitted you to do such deeds and has not placed sin in them. However, the one who attacks the honor of his brother in any way, then certainly that is great sin.” The Bedouin thereafter asked, “O Rasul of Allah (sallallahu ‘alaihi wasallam)! Will we be sinful if we do not adopt medical treatment?” Rasulullah (sallallahu ‘alaihi wasallam) replied, “Adopt medical treatment, o servants of Allah! For indeed, besides old age, Allah Ta‘ala has not placed any sickness without a cure.” The Bedouin then asked, “O Rasul of Allah (sallallahu ‘alaihi wasallam)! What is the best favor that a servant can be blessed with (by Allah Ta‘ala)?” Rasulullah (sallallahu ‘alaihi wasallam) replied, “Excellent character”.
