Thanku also for accepting the truth. For knowing the correct interpretation of those ayah, you can refer to authentic tafsir of Qur'an like Tafsir Ibn Khathir, Ma'ariful Qur'an by Mufti Muhammad Shafi'i r.a. etc.

I don't think so izaree had questioned there or that he was replying to ME, but in case, if you want to ask me what Izaari was telling there,
so i can hardly interpret him that he *meant* to say or what is suppose to know for us is that even munafiqeen say that they are muslim and their religion is islam but they are missing the important aspect of religion Islam know as Iman, which means affirmation and confirmation in the heart. in the heart they still deny the verses of Qur'an or anything which prophet Muhammad sallallahu alihi wa sallam has brought along with him, they deny it, due to this nifaaq in heart they are not muslims. They are known as munafiqeen who even saying that islam their religion they are not beleiving the truth.

Ihsan is the aspect of Islam which means to strive for excellence in achieving piety. Also known as Tasawwuf/Sufism in the context of various branches of the Islamic sciences that has developed, Tasawwuf is a branch of Islamic knowledge which focuses on the spiritual development of the Muslim. There are verses of Qur'an and Hadith for its importancy, like Hadith-e-Gabriel.

I hope I answered more now.
