so u mean that the man converted to islam coz he want to be 'richest' like saudis....am smelling a 'search for the wealth' kinda intentions in his statement....or may be he want to say he got a strong belief in the above mentioned verse....am not allowed to assume...and also i believe that "inna mal a'amalo bin'niyyat"....

secondly,if this is the case then why only saudis....why not bangladeshis,pakistanis,sudanese and other poor muslim countries....dont u agree they also said ALLAHU AKBAR....

the answer is simple..."Truly, your Lord expands the provision for whom He wills and straitens (for whom He wills). Verily, He is Ever All-Knower, All-Seer of His servants." Soorah al-Isra (17): 30
