Refraining from Seeing a Doctor Unless Necessary

Imam al-Kāẓim, peace be upon him, advised:
اِدْفَعوا مُعالَجَةَ الاَطِبّاءِ مَا انْدَفَعَ الدّاءُ عَنْكُمْ، فَاِنَّهُ بِمَنْزِلَةِ الْبِناءِ قَليلُهُ يَجُرُّ اِلى كَثيرِة.
“Refrain from seeking medical treatment when the illness is kept at bay, for treatment is akin to building; a little of it leads to much.”
ʿIlal al-Sharāyiʿ 465
