" After we have performed the istikharah, we should tawakkaltu 'alallah. We surrender everything to Him. If the person that we intended to be with is not the result of our istikharah, then bear in mind that that is the best, the BEST decision for us. Because Allah will give us someone much better than that person, and that person will be given someone who is way much better than us. Don't be sad, because Allah knows best. "
