“Let there be no compulsion in religion: Truth stands out clear from Error: whoever rejects evil and believes in God hath grasped the most trustworthy hand-hold, that never breaks. And God heareth and knoweth all things.” 2:256
meet other people from other cultures
“O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise (each other). Verily the most honored of you in the sight of God is (he who is) the most righteous of you. And God has full knowledge and is well acquainted (with all things).”
Quran 49:13
Do good to others
God does not forbid you from being good to those who have not fought you over religion or driven you from your homes, or from being just towards them. God loves those who are just. God merely forbids you from taking as friends those who have fought you over religion and driven you from your homes and who supported your expulsion. Any who take them as friends are wrongdoers. (Qur’an, 60:8-9)
respect Monasteries, Churches and Synagogues since they are God’s houses
…if God had not driven some people back by means of others, monasteries, churches, synagogues and mosques, where God’s name is mentioned much, would have been pulled down and destroyed. God will certainly help those who help Him-God is All-Strong, Almighty. (Qur’an, 22:40)
don’t be abusive toward disbelievers and pagans
“Do not revile those whom they invoke other than Allah.” (6:108)
Be respectful and gentle when you preach to others
Invite (people) to the way of your Lord with wisdom and good counsel. And argue with them in the best of manners. Surely, your Lord knows best the one who deviates from His way, and He knows best the ones who are on the right path.” (16:125)
