Allahumma taqabbal minkum.

I too experienced many similar events while on Hajj. Al hamdullilah, we have a very balanced, humble Imam here in OKC that I would call to get advise on what was happening and he would remind me and advise me to have patience and what I was there for. I learned about really having patience and appreciating the blessings Allah swt has given us. I think the only time I almost lost control of myself was while doing tawaaf in Majid Al Haram, I got ran over by the same wheel chair three times in a row. The first time really hurt! I made a hollor of pain and turned around to see what happened. I gave a reactionary look of pain and anger to the driver; but didn’t say anything. After the third time, I reminded him “you’ve ran me over three times now brother!” I guess I scared him because he quicky moved on around me. I then felt guilty about getting upset. Up to that point I was happy with myself that I hadn’t got upset even after witnessing many of the same conflicts that you previously mentioned. I realize that Allah swt will test us in so many ways.
May Allah swt bless us with patience, understanding, knowledge, and good understanding of how to live this deen, ameen. May Allah except journey to the sacred House, ameen.

Jazakumu Allahu Khairan.
