What happens if an infidel wants an Islamic mortgage?
Well, according to the Quran, it's best not to ask:
Quran (4:89) - “They but wish that ye should reject Faith, as they do, and thus be on the same footing (as they): But take not friends from their ranks until they flee in the way of Allah (From what is forbidden). But if they turn renegades, seize them and slay them wherever ye find them; and (in any case) take no friends or helpers from their ranks.”
Quran (5:33) - “The punishment of those who wage war against Allah and His messenger and strive to make mischief in the land is only this, that they should be murdered or crucified or their hands and their feet should be cut off on opposite sides or they should be imprisoned; this shall be as a disgrace for them in this world, and in the hereafter they shall have a grievous chastisement”
Quran (8:12) - “I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike off every fingertip of them”
Bukhari (52:177) - Allah's Apostle said, “The Hour will not be established until you fight with the Jews, and the stone behind which a Jew will be hiding will say. “O Muslim! There is a Jew hiding behind me, so kill him.”
Muslim (1:30) - “The Messenger of Allah said: I have been commanded to fight against people so long as they do not declare that there is no god but Allah.”
Bukhari (11:626) - [Muhammad said:] “I decided to order a man to lead the prayer and then take a flame to burn all those, who had not left their houses for the prayer, burning them alive inside their homes.”
Tabari 9:69 “Killing Unbelievers is a small matter to us”
Perhaps the stupid infidel should consult his tax adviser.
He would learn that interest on residential mortgages is tax deductible, but rent-to-own rental payments are not.
