Allah reveals that He has created a way and a method for all nations. Throughout history, He has sent Prophets to people to inform them of His laws, commands, and prohibitions. Essentially, all Prophets have invited their nations to believe in and worship Allah and to abide by the limits He has established for humanity. In other words, all true religions in their original state are based on the principles of not associating others with Him and of working to win His good pleasure, compassion, and Paradise. All nations are expected to follow Allah's will without fail and to do good deeds in order to earn His reward:

We have appointed a law and a practice for every one of you. Had Allah willed, He would have made you a single community, but He wanted to test you regarding what has come to you. So, compete with each other in doing good. Every one of you will return to Allah, and He will inform you regarding the things about which you differed. (Qur'an, 5:48)

The People of the Book were given a different law than the Muslims, but all sincere Jews, Christians, and Muslims are required to submit wholeheartedly to Him, do what is good, and compete in doing good deeds. All of them who believe in Allah's existence and unity and the Hereafter and do good deeds are, in reality, following the true religion revealed to Abraham (pbuh). Allah reveals that Adam (pbuh) was the first of a long line of Prophets, to which his descendents Noah and Abraham (peace be upon them all) also belong:

"Peace be upon Noah, among all beings." That is how We recompense the good-doers. He truly was one of Our servants who believes. Then We drowned the rest. One of his followers in faith was Abraham. (Qur'an, 37:79-83)

The Qur'an reveals that Abraham (pbuh) was a haneef, meaning one who surrenders to Allah's will, not compromising in any way on his religion, and being devout. In one verse, Allah commands Prophet Mohammed (may Allah bless him and grant him peace) to abide by this religion:

Then We revealed to you: "Follow the religion of Abraham, a man of pure natural belief. He was not one of the idolaters." (Qur'an, 16:123) Abraham's (pbuh) sons, grandchildren, and other devout Muslim descendents all abided by his religion, for, Who would deliberately renounce the religion of Abraham, except someone who reveals himself to be a fool? We chose him in this world, and in the Hereafter he will be one of the righteous. When his Lord said to him: "Become a Muslim!" he said: "I am a Muslim who has submitted to the Lord of all the worlds." Abraham directed his sons to this, as did Jacob: "My sons. Allah has chosen this religion for you, so do not die except as Muslims." Or were you present when death came to Jacob and he said to his sons: "What will you worship when I have gone?" They said: "We will worship your Allah, the Allah of your forefathers, Abraham, Ishmail and Isaac - one Allah. We are Muslims submitted to Him." (Qur'an, 2:130-33)

As we can see, the religion followed by Abraham (pbuh) represents the common ground among Muslims, Jews, and Christians. Love, faith, and respect for Abraham (pbuh) are just as important to Muslims as they are for Christians and Jews. However, those who follow his morality are the ones who are closest to him. He was exuberant in his faith in Allah, loved him deeply, followed all of His commands willingly, and thus was an example for all humanity. As Allah says:

The people with the strongest claim to Abraham are those who followed him and this Prophet, and those who believe. Allah is the Protector of the believers. (Qur'an, 3:68)

Therefore, all Jews and Christians, who believe wholeheartedly in Allah, like Abraham (pbuh) and the believers who followed him, must only turn to Allah and follow this great Prophet's example of virtue, sincerity, and insight. The best way to show one's love, obedience, and closeness to the Prophets is by emulating them. Muslims do not discriminate among all of the Prophets and what was revealed to them, for Allah commands:

Say: "We believe in Allah and what has been sent down to us, what was sent down to Abraham and Ishmael, Isaac and Jacob, and the Tribes; what Moses and Jesus were given; and what all of the Prophets were given by their Lord. We do not differentiate between any of them. We are Muslims submitted to Him." (Qur'an, 2:136)
