President Obama is naive to think he can negotiate with Iran. All he has to do is read the Qur'an. Sura 9:3-5 talks about treaties with pagans, i.e. non-Muslims. In verses three and four the Qur'an says to honor treaties for a time.
In Abdullah Yusuf Ali's commentary he indicates the period of time is four months. In verse five it says, "But when the forbidden months Are past, then fight and slay The Pagans wherever ye find them, And seize them, beleaguer them, And lie in wait for them In every stratagem (of war); But if they repent, And establish regular prayers And practice regular charity, Then open the way for them; for God is Oft-forgiving, Most merciful." In other words, let them alone if they become good Muslims.
But what about the peaceful verses such as Sura 2:256? "Let there be no compulsion in religion."
Fundamental Imams interpret the Qur'an using the doctrine of abrogation. In a situation of a contradiction, the verse revealed to Muhammad last abrogates (nullifies) the verse revealed before. Sura 9:1-29 were the last verses revealed to Muhammad before his death except for Sura 110 which is kind of a tone poem. Hence, Sura 9:3-5 abrogates Sura 2:256 which was revealed earlier in the Medina period.
Hence, fundamental Muslims will make treaties only if they are not strong enough militarily and will honor them until they have enough power politically or militarily to take over. That is why negotiating with Iran is foolhardy.
