Is it reprehensible for a fiancée to dislike her fiancé's preference for his brother's Umrah trip over her going with him on the Umrah trip he promised her as a substitute for the wedding, and her feeling of injustice?

Whoever dislikes the loss of something should be mindful of the following:

1. Not to transform natural dislike into a religiously forbidden hatred that leads to unjustly accusing people. 2. Beware of disliking the decree of Allah. There is no harm in disliking what has been decreed, but disliking the decree itself is unanimously forbidden. 3. Beware of disliking Allah's blessings upon others and envy, for this is a forbidden hatred. 4. Allah's grace is not contingent on financial ability. Whoever intends good but is unable to do it, Allah records its reward for them. 5. Contentment with Allah's decree and patience over what has been missed is good, for the patient will be given their reward without account.
