Then, when he turned his face towards (the land of) Madyan, he said: “I do hope that my Lord will show me the smooth and straight Path.”
And when he arrived at the watering (place) in Madyan, he found there a group of men watering (their flocks), and besides them he found two women who were keeping back (their flocks). He said: “What is the matter with you?” They said: “We cannot water (our flocks) until the shepherds take back (their flocks): And our father is a very old man.”
So he watered (their flocks) for them; then he turned back to the shade, and said:”O my Lord! truly am I in (desperate) need of any good that Thou dost send me!”
Afterwards one of the (damsels) came (back) to him, walking bashfully. She said: “My father invites thee that he may reward thee for having watered (our flocks) for us.” So when he came to him and narrated the story, he said: “Fear thou not: (well) hast thou escaped from unjust people.”
Said one of the (damsels): “O my (dear) father! engage him on wages: truly the best of men for thee to employ is the (man) who is strong and trusty”….
He said: “I intend to wed one of these my daughters to thee, on condition that thou serve me for eight years; but if thou complete ten years, it will be (grace) from thee. But I intend not to place thee under a difficulty: thou wilt find me, indeed, if Allah wills, one of the righteous.”
He said: “Be that (the agreement) between me and thee: whichever of the two terms I fulfil, let there be no ill-will to me. Be Allah a witness to what we say.”
(Quran 28:22-28)
Compare the case in point above, with Chapter 7 of the Holy Quran, where in verse 21, Satan “swore to them [Adam and Eve] both, that he was their sincere adviser.” There is the image of Satan and the reality that God knows. No social contract or agreement, does not accept advice or inspiration from Adam and Eve, upon them peace, when they sought repentance from God, and false claims to his sincerity – whereas Prophet Shuaib tells Moses, upon them peace: “thou wilt find me, indeed, if Allah wills, one of the righteous.”
