@a-town boy.
Don't waste your time here my friend, its wasting your precious minutes of your life, believe me. Nothing will stop people like this. Shaitan said he would come down and try and lead the believers astray. People like this will stop at no end to hurt others, and come in the way of Allah. Again, read the following verses.
(Surah 5:13) "But because of their breach of their covenant, We cursed them, and made their hearts grow hard; they change the words from their (right) places and forget a good part of the Message that was sent them, nor wilt thou cease to find them- barring a few - ever bent on (new) deceits: but forgive them, and overlook (their misdeeds): for Allah loveth those who are kind"
(Surah 33:48) "And obey not (the behests) of the Unbelievers and the Hypocrites, and heed not their annoyances, but put thy Trust in Allah. For enough is Allah as a Disposer of affairs."
Salaam,
Brother, how are you going to defend someone with quranic ayats when that person don't even believe in Quran? If he believes in it then he doesn't practice what Allah has reveled in Quran?
Most Ismaili said that AgaKhan is walking talking Quran. What didn't Allah reveled in Quran? No gambling? No Sharaab? Pay Zakat? Namaz which is gift from Allah to Rasulullah (Saw), do Ismaili practice what is in Quran and Sunnah it?
