Love Him

If your heart is enslaved by someone who is forbidden for him: One of the main causes for this miserable situation is turning away from Allah, for once the heart has tasted worship of Allah and sincerity towards Him, nothing will be sweeter to it than that, nothing will be more delightful or more precious. No one leaves his beloved except for another one he loves more, or for fear of something else. The heart will give up corrupt love in favour of true love, or for fear of harm.

-Ibn Taymiyyah
