Well, i totally agree that we cannot judge who is superior to Allah (SAT), it is nothing like religious men are only in arabia, nor Allah(SAT) count our deeds based on our nationality or deeds of our fore fathers. Every one is individually responsible for his own deeds.
And for CHEEGUM right now i remember only one verse from holy Quraan where Allah(SAT) Himself says that Quraan is easy to learn( i dont remember the surah, so please if some can or i will search for it if you want)
WALAKHAD YASSARNAL KHUR-AANA LIZZIKR FAHAL MIM-MUDDAKIR
AND INDEED WE HAVE MADE QURAAN EASY TO UNDERSTAND AND REMEMBER SO IS THERE ANY ONE WHO RECEIVE ADMONITION?
so we should never think that Quraan is the most difficult book to understand or arabic is the most dificult language to learn. It is the most easiest one. I didnot heard of any non muslim who has byhearted his/her religious book. But mashallah just when we turn to Quraan we see many people who have learned Quraan byheart, i even saw many kids below 6 years who know Quraan by heart.May Allah make us all among those who have learned Quraan.Ameen!
