>Also, are there safe and sound resources available for those who question and are seeking answers?

Here are the resources:

• Quran: https://quran.com/
  
• Hadiths/Short accounts of Muhammad's life: https://sunnah.com/
  
• Tafseer/Exegesis of the Quran: Al-Jalalayn
  
• Seerah/Biography of Muhammad: The Sealed Nectar | Free version
  
• WikiIslam (Muslims will never acknowledge it as a good source of info because it's critical of the ideology they push but it's legit for the most part): http://wikiislam.net/wiki/Main_Page
  
• Critical analysis of Islam by a Christian speaker named Jay Smith (his bias is apparent but his info is good): Youtube lecture
