How do I break up with my fiancée amicably?

If the suitor is compelled to break off the engagement, there must be a strong justification for it, as it causes harm to the fiancée and her family. The breaking off should be done in the best possible manner, with an apology that alleviates embarrassment from the girl and her family and preserves their feelings. As for financial rights and the dowry paid before the contract, these are subject to the rulings of Sharia (definition) in that regard.
