What is the ruling on seeking medical treatment for an illness, and is it better to forgo it as that would be closer to reliance on Allah (tawakkul), and what is the authenticity of the report narrated from Abu Bakr Al-Siddiq regarding his abstention from seeking medical treatment?

The correct view, held by the majority of scholars, is that seeking medical treatment (Tadawi) is desirable and permissible. It does not contradict reliance upon Allah (Tawakkul); rather, taking appropriate means is part of perfect reliance. Seeking treatment with lawful and permissible remedies, such as the Qur'an, ruqya (incantation) according to Islamic law, and cauterization (kayy) when necessary, helps in fulfilling the interests of the individual and their family. As for one who chooses not to seek treatment, there is no sin upon them. However, if the need becomes severe and its benefit is anticipated, seeking treatment becomes more emphasized due to its numerous benefits. The opinion that refraining from treatment is better is weak. The argument based on the hadith about the seventy thousand who will enter Paradise without reckoning only refers to refraining from seeking ruqya (requesting it from others) and refraining from cauterization, not from taking means in general. Indeed, only tuyarah (superstitious omens) is prohibited in the hadith.
