I'm surprised at this, Allah's last book to his people just isn't good enough for some. What exactly is the point of Qur'an for such people? Whenever someone asks to read or know about Islam, the automatic answer should be Quran, rather than some book written by man. Who can explain his religion better the creator or some puney human? I'd go with God. salam saqqib
Quran and Seerah at the same time, it's a tried and tested formula bro, ask the converts, they convert mainly because of the Quran nothing else, obviously none of them would understand the whole thing but it wouldn't stop them from understanding the basic message of Islam.
