Hadith 14:4
Abu Bakr narrated to us, he said: Ibn 'Uyaynah narrated to us, from Ziyad ibn 'Alaqah, from Usamah ibn Sharik, who said: I witnessed the Bedouins asking the Messenger of Allah, may Allah bless him and grant him peace. He said: "Seek treatment, servants of Allah, for Allah has not placed a disease except that He has placed with it a cure, except for old age."
حدثنا أبو بكر قال حدثنا بن عيينة عن زياد بن علاقة عن أسامة بن شريك قال شهدت الأعراب يسألون رسول الله صلى الله عليه وسلم فقال تداووا عباد الله فإن الله لم يضع داء إلا وضع معه شفاء إلا الهرم
