Medicine

The Islamic rule is same for any medical treatment including dentistry which says that female is not allowed to be touched by a male doctor except in emergency when no female doctor is available. Muslim female should go to female doctors only even in dentistry.

Muslim is allowed to study any system of medicine as far as it is a medical science with out any additional non medical opinions. Non Muslims' opinions are not part of the medicine but their way in understanding or dealing with it. We study the medical science and leave the non Muslim myths. Our Muslim history has evidence that we take medical knowledge and other worldly sciences from any expert being Muslim or non Muslim. No doubt, we have great treasure of medical knowledge in thousands of narrations and sayings of the Prophet (SAWA) and Ahlul Bayt (AS). That does not stop us from studying any other source of medical knowledge.

Islamic rules forbidding seeing or touching other gender (Non Mahram) are very clear but exceptions come if there is a real necessity to save life. Necessity must be assessed and the exception should meet no more than the necessity. Any act more than the real necessity is not permissible.

It is not allowed to touch non Mahram but only in emergency like life saving or medical emergency etc.

Touching other gender does not invalidate Wudhu, despite of the opinion of Shaafi’ee sect that it invalidates. Their opinion is based on misunderstanding the Quranic verse أو لا مستم النساء. Even most of Sunni scholars do not accept the opinion of Shafi’ee sect in this matter.

Permanent sterilization which makes pregnancy impossible for ever to is not allowed, while any temporary measure to prevent pregnancy for a while (even for years) is allowed.
