Can I follow or engage with non-Muslim friends' content on social media?

Yes — following non-Muslim friends on social media to see their posts, comment supportively on ordinary life updates, or maintain a genuine friendship is generally permissible; Islam does not prohibit friendly, respectful social relationships with non-Muslims, and the Quran and Sunnah are full of examples of the Prophet ﷺ dealing kindly and fairly with non-Muslim neighbors, relatives, and acquaintances. The general principle scholars apply is the same one that governs offline friendships: maintain good character (akhlaq), don't compromise your own religious practice, and don't actively participate in or endorse specifically religious content that contradicts Islamic belief (e.g., liking or celebrating content tied to another religion's worship).

Where scholars advise more caution is content, not the relationship itself: engaging with posts that involve clearly haram content (immodesty, alcohol, gambling, content mocking Islam) crosses from ordinary social courtesy into something that should be avoided regardless of who posted it. In practice, most scholars frame this simply as "treat the online relationship the way you'd treat the offline one" — good conduct and honest, respectful friendship are encouraged, while participation in specifically un-Islamic religious content is not.
