Allāh ﷻ tells us in the Holy Qur’ān that you may want something, but it is not good for you, and you may dislike something, but it is good for you. We do not know the wisdom in what Allāh ﷻ has decreed. Try hard, do everything you can, and then leave it to Allāh ﷻ. Ḥajj has its hardship, but it is a test from Allāh ﷻ, and He ﷻ gives abundant reward for it. Ask Him ﷻ to give what is good and keep away what is harmful.
