First of all ( I know that this is off topic but), i know that Muslims are divided into different sects but dividing Islam is haram. You're either a Muslim or a non muslim not a "Sunni" or "Ismaili". As a Muslim you should follow the Quran and the Hadiths. If you follow the Quran and the hadiths your a Muslim. If you follow Imam Ali (as) you're a Muslim. There is no need of calling yourselves Ismaili. Allah (swt) says to call yourselfs Muslims “Who is better in speech than one who calls (men) to Allah, works righteousness, and says, ‘I am of those Who bow in Islam (Muslim)?’ ” [Al-Qur’an 41:33] The Qur’an says “Say I am of those who bow in Islam”. In other words, say, “I am a Muslim”.
The problem with "Ismailis" is that they classify themselves as Ismaili when they should classify themselves as Muslims. Also Prophet Muhammed pbuh the last prophet who Allah swt sent prayed 5 times a day whereas Ismailis don't and Ismailis don't even follow the sunnah like growing a beard, women wearing a hijab or even praying in a masjid.
The Quran has evidence that Islam shouldn't be divided The Glorious Qur’an says: “And hold fast, all together, by the rope which Allah (stretches out for you), and be not divided among yourselves;” [Al-Qur’an 3:103]
"Obey Allah, and obey the Messenger” [Al-Qur’an 4:59] All the Muslim should follow the Qur’an and authentic ahadith and be not divided among themselves.
Secondly, Also do you think that selling bombs to terrorist is haram? You're only selling the bomb right? It doesnt matter that the bombs are used to kill innocent people? Wrong!!! By selling alcohol to a Muslim or a non Muslim you're aiding them in disobeying Allah swt. You're helping them kill themselves and distancing them from Allah. It doesn't matter if the buyer is non Muslim, Because everyone is born muslim.
Bro, believe whatever you want to believe but I will believe in the words of Allah swt and the prophet muhammed saw
