As-salamu alaykum,

The desire to make hajj is in the heart of all Muslims. Sadly, not all Muslims can afford to make hajj, so you are not alone. While that does not change the way you feel, the way you feel is indeed normal amongst Muslims who cannot thus far make hajj. I would kindly suggest that insha’Allah you make dua to Allah the He make it possible for you to someday make hajj. As you have not been able to make hajj yet, there is nothing in your future that says you never will. Only Allah knows, and Allah is most merciful to His servants. I would kindly suggest that you think and speak in the positive. When you speak of hajj, state that insha’Allah you too are looking forward to going. Try to get with other Muslims in your similar situation and develop a plan of action for the future in which as small group, you can save up money and go to hajj. Check out hajj opportunities at Islamic centers and Masjids to compare prices and options. You may be surprised at discounts you may get in groups.
As far as your uncle is concerned, it is natural that he is happy and gets excited when he talks about his hajj experience. However if he is indeed boastful that is not a good thing. Allah does not like boasting. Perhaps this is also a test for you concerning patience, concerning trust in Allah (iman) as well as learning not to be a jealous one, as jealousy is as despised by Allah as is boasting. While we are all human and do get jealous at times, it is something we should strive to over-come. Perhaps if you listen to others who have made hajj and instead of feeling jealous, you develop a feeling of love and happiness for them, you may reap the blessings of hajj sooner. As a test, this is a difficult one to over-come! For our love for Allah SWT is so immense and we do crave to make hajj as others have done. However, if we cannot feel true joy and happiness for those who have had this blessing, how will we handle the blessing when it comes to us going? Would we become boastful? Would we want others to be jealous of us and harbor negative thoughts? We should “want for our brothers and sisters what we want for ourselves”. This includes opportunities to make hajj.
Thus I kindly recommend you make duaa to Allah to remove feelings of jealous, increase your wealth so you are able to make hajj , and insha’Allah help you find joy in your Muslim brothers and sisters who are able to make hajj. These things will bring you closer to Allah and insha’Allah bring you closer to making hajj one day soon. We wish you the best.
