1. In Srimadbhagavadgita, which was composed long before the creation of Muslim religion or for that matter many other religions, The Lord says clearly that, "Shreyaan Swadharmo vigunaha, Paradharmaat Swanushtitaath, Swadharme Nidhanam Shreyaha, Para Dharmo Bhayavahaha", meaning, following one's own faith is better than another faith that is better followed. Never mind if one's own faith has certain defects. Another faith is dreadful. It is better to die following one's own faith than to live following another faith.
2. When that being the case, no right thinking Hindu will fall into the fold of another religion, howsoever flawless it may be. I have high reverence towards Muslims and Quran. In fact several of my best friends are muslims. We all live in harmony following our own faiths. I appreciate your last sentence & respect you for that. Khuda Haafiz!
