النساء
وَلِلَّهِ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ ۚ وَكَانَ اللَّهُ بِكُلِّ شَيْءٍ مُّحِيطًا 126
This refers to the superiority of Islam which is full submission to the will of Allah, over all the other religions. Three criterions are introduced here as the standards of judging the best of religions:
1- Full submission of the whole self to Allah, the only one true God, Who is the creator of the universe.
2- Being good in words and deeds, and doing good and justice to All.
3- Following the creed of ABRAHAM the KHALIL OF ALLAH.
WHAT DOES KHALIL MEAN?
ABRAHAM is one of the five arch prophets of Allah in Muslim theology with the title of KHALIL- ALLAH; which may mean the friend of Allah, or one who has purified himself for Allah. In spite of all that dignity and title, in the theology of Islam, he is no more than a mortal man, chosen by Allah as Messenger, and ultimately as God's friend. ABRAHAM'S creed, and his strict belief in Monotheism, and his ardent love for the only true God, has been the foundation and origin of the three great religions founded by Moses, Jesus, and Mohammad.
