The one for Me is that you worship Me and no one else, and the one for you is that I will reward you for your deeds as much as you need, and the one between Me and you is that you have to pray and praise Me and I will answer you, and the one between you and people is that you have to love for people what you love for yourself.
Some tidings mentioned that God revealed a book written in Syriac made of tweny one pages, and it is the first book ever to be revealed on human beings, and in it there was one thousand thousand [a million] tongues, no people with one of these tongues would understand the other without education, and Adam has the knowledge in every tongue and can speak it better than its native speakers, and contained also the clues of God and His worshippings, judgements, rules and laws..etc from Ibn 'Abbâs that he said: When God created Adam, and Breathed in him from His Spirit, he sneezed and God inspired him to thank Him so he said: Praise be to Allah, Lord of the Worlds, so his Lord said to him: mercy of your Lord be upon you.
And when God made Angels prostrate before him, he got exclaimed and said: O Lord, You created a creation that is beloved to You more than me?
but God didn't answer him, then he asked again, and God didn't answer, then he asked for the third time but god didn't answer him, then God did say: Yes, and for them only I did create you, then he said: O Lord let me see them, then God ordered the Angels of the veils to left off the veils, and when they did and Adam looked, he found out five ghosts in front of the Throne, then he said: O Lord who are they?
then God did say: O Adam, this is my prophet Muhammad, and this is 'Ali the Prince of Believers, the cousin of my prophet and his viceroy, and this is Fâtima the daughter of my prophet, and these two are Al-Hasan and Al-Husain the sons of 'Ali and sons of my prophet, then He said: and they are your descendants, so Adam got happy for this.
And when he did the sin he said: O Lord I ask You by Muhammad and 'Ali and Al-Hasan and Al-Husain to relent toward me, and so God relented toward him by them, and this is what is meant by God's saying "Then Adam received from his Lord words (of revelation), and He relented toward him" (Al-Baqarah: 37). When Adam got down on earth, he made a ring and carved on it: Muhammad is the prophet of God and 'Ali is the Prince of Believers.
