Lights on the way

While this alignment between the Prophet's teachings and scientific findings can be seen as evidence that his guidance is true and beneficial, the main source of belief in his prophethood and message is based on faith, the miracles he performed, his character, the consistency of his message with the Quran, and the transformative impact of his teachings. The Hadith you mentioned about turning off lights when going to bed is a recommendation from the Prophet Muhammad (PBUH) that aligns with modern scientific research. For us (muslims), the consistency between the Prophet's teachings and modern scientific discoveries can strengthen our faith. 

Indeed, Prophet Muhammad (PBUH) has provided guidance on how to deal with dogs, particularly in terms of cleanliness and hygiene.This guidance aligns with the understanding that dogs' saliva contain harmful germs or impurities, which pose a risk to human health. It is important to note that Islam does not promote hatred towards dogs. Instead, it encourages a responsible appraoch to dealing with dogs in a way that maintains cleanliness and avoids potential harm. Dogs can be useful for guarding property, herding livestock, hunting, and other purposes, but their saliva is impure (najas) in terms of Islamic ritual purity. As muslim, we should follow the Prophet's teachings and maintan proper cleanliness when dealing with dogs, including keeping them away from food and other items used by human, as a means of safeguarding health and adhering to religious guidance.
