Let me tell you something... never ever trust an Arab. I have dealt with them in business only to have been cheated. This happened with me twice and I lost over 50k (lebanese guy). He would sweet talk me as a "Bakistani brother" and would talk crap about Indians he had dealt with before (was prob talking crap about Pakistanis to these Indians as well). Later I told myself I should not judge all arabs to be the same as such a thing would be small minded and against Islam, so took a dive into a small electronics shop in Dubai with what seemed to be a nice gentlement from Egypt... only to be lied to, cheated behind my back, etc... ended up selling the business with a loss and nothing to show.
I vowed to never trust another Arab again but still wanted to seek some guidance... so I visited an Imam at my local mosque, told him about the whole situation and how I was cheated. The imam who was from Uzbekistan stated something which stuck with me to this day... he said something along the lines of "Brother there is a saying that Allah had sent last Prophet to the Arabs for a reason (them being the most vile, barbaric, and dishonest of people)."
The best advice i can give my Pakistan bretheren, drop the Ummah fantasy like a hot rock, never trust or sympathize with these Arabs. They are infact not just cousins but brothers of the jews. Atleast there are many great jews out there who have done great for humanity such as Bill Gates, but these Arabs will backstab other muslims in a second for a small benefit.
How could anyone be so negligent??? an Arabs attention span is as short as a 2 year olds. They are wild natured and hot blooded people who will destroy themselves. Not even Islam could civilize them.
