What is the prohibited al-muwalat (allegiance/support), what are the limits of interaction with non-Muslims at work, is it permissible to supplicate for their guidance by specifically naming them, and what is the ruling on reading misconceptions (shubuhat) in order to refute them?

It is permissible to supplicate for a disbeliever's guidance using any wording, such as "O Allah, guide so-and-so." It is advisable to strive diligently in understanding the religion from its reliable sources to increase faith and comprehend the legal rulings. As for delving extensively into reading dubious arguments and refutations, this should be undertaken by those qualified for it, out of fear that a dubious argument might cling to the heart of someone with little knowledge.
