And Abraham said unto his eldest servant of his house, that ruled over all that he had, Put, I pray thee, thy hand under my thigh:
And I will make thee swear by the Lord, the God of heaven, and the God of the earth, that thou shalt not take a wife unto my son of the daughters of the Canaanites, among whom I dwell. Genesis 24:2&3
And it came to pass after the death of Abraham, that God blessed his son Isaac; and Isaac dwelt by the well Lahairoi. Genesis 25:11
O People of the Scripture! Why will ye argue about Abraham, when the Torah and the Gospel were not revealed till after him? Have ye then no sense? Koran 3:65

And Our messengers cam unto Abraham with good news. They said: Peace! He answered: Peace! and delayed not to bring a roasted calf.
And when he saw their hands reached not to it, he mistrusted them and conceived a fear of them. They said: Fear not! Lo! we are sent unto the folk of Lot.
And his wife, standing by laughed when We gave her good tidings (of the birth) of Isaac, and, after Isaac, of Jacob.
She said: Oh woe is me! Shall I bear a child when I am an old woman, and this my husband is an old man? Lo! this is a strange thing!
They said: Wonderest thou at the commandment of Allah? The mercy of Allah and His blessings be upon you, O people of the house! Lo! He is Owner of Praise, Owner of Glory!
And when the awe departed from Abraham, and the glad news reached him, he pleaded with Us on behalf of the folk of Lot.

Recite unto them the story of Abraham:
When he said unto his father and his folk: What worship ye?
They said: We worship idols, and are ever devoted unto them.
He said: Do they hear you when ye cry?
Or do they benefit or harm you?
They said: Nay, but we found our fathers acting on this wise.
He said: See now that which ye worship,
Ye and your forefathers!
Lo! they are (all) an enemy unto me, save the Lord of the Worlds,
Who created me, and He doth guide me,
And Who feedeth me and watereth me.
And when I sicken, then He healeth me,
And Who causeth me to die, then giveth me life (again),
And Who, I ardently hope, will forgive me my sin on the Day of Judgment.
My Lord! Vouchsafe me wisdom and unite me to the righteous.
And give unto me a good report in later generations.
And place me among the inheritors of the Garden of Delight,
And forgive my father. Lo! he is of those who err.
And abase me not on the day when they are raised, Koran 26:69-87
And when (his son) was old enough to walk with him, (Abraham) said: O my dear son, I have seen in a dream that I must sacrifice thee. So look, what thinkest thou? He said: O my father! Do that which thou art commanded. Allah willing, thou shalt find me of the steadfast. Koran 37:102
