What are the best ways to invite non-Muslims to Islam, and is it permissible to give them a copy of the Noble Qur'an that includes the verses in Arabic with their translation?

It is permissible to give a disbeliever a translated copy of the meanings of the Holy Quran, as long as it does not include the Quranic text in Arabic. One must repent to Allah for what happened previously, while attempting to retrieve the translated surahs that contained the Quranic text. It is not permissible for a woman to take a male friend who is a stranger to her, even if the intention is good, for Islam prohibits relationships between sexes outside the bounds of marriage. There are regulations for studying in mixed schools and residing in lands of disbelief.
