وَلَقَدْ جَاءَتْ رُسُلُنَا إِبْرَاهِيمَ بِِلْبُشْرَى قَالُوا سَلَامًا قَالَ سَلَامٌ فَمَا لَبِثَ أَنْ جَاءَ بِعِجْلٍ حَنِيذٍ * فَلَمَّا رَأَى أَيْدِيَهُمْ لََ تَصِلُ إِلَيْهِ نَكِرَهُمْ وَأَوْجَسَ مِنْهُمْ خِيفَةً قَالُوا لََ تَََفْ إِنََّّ أُرْسِلْنَا إِلََ قَوْمِ لُوطٍ * وَامْرَأَتُهُ قَائِمَةٌ فَضَحِكَتْ فَبَشَّرْنََّهَا بِِِسْحَاقَ وَمِ نْ وَ رَاءِ إِسْحَاقَ يَعْقُوبَ * قَالَتْ يََ وَيْلَتََ أَأَلِدُ وَأَنََّ عَجُوزٌ وَهَذَا بَعْلِي شَيْخًا إِنَّ هَذَا لَشَيْءٌ عَجِيبٌ * قَالُوا أَتَعْجَبِينَ مِنْ أَمْرِ اللََِّّ رَحَْْتُ اللََِّّ وَبَرَكَاتُهُ عَلَيْكُمْ أَهْلَ الْبَيْتِ إِنَّهُ حَِْيدٌ مََِيدٌ * )الهود الآية ٦٩ - ٧٣ )

Indeed, Our messenger-angels came to Ibraheem Alaihis Salaam with good new (that he will father a son and have grandson afterwards) and greeted him with (the words of) Salam. He said, “Salam (peace be upon you too),” and did not hesitate to bring a roasted calf (to host them). (However, they did not partake of the meal because angels do not eat.) When he noticed that their hands were not reaching out towards it (to eat), he grew fearful of them (thinking that they have come to harm him). They said, “Do not fear. We (are angels who) have been sent to (destroy) the nation of Loot Alaihis Salaam. His wife (Sarah) standing by, laughed (with happiness) as we conveyed to her the good news (that she would be giving birth to a son by the name) of Ishaaq , and (she will have a grandson by the name of) Yaqoob Alaihis Salaam. She said (in astonishment), “Oh dear! Shall I bear a child when I am an old woman ( of more then 80 years, some say: 99 years) and my husband here is an old man (of over 100 years, some say: 120 years)? This is indeed a strange event!” They (the angles) said, “Are you surprised (wondering) at the command (and powers) of Allah  (who can do anything? May Allah’s mercy and blessing be on you, O members of the household (of Ibraheem Alaihis Salaam). Verily He is worthy of all praise, the Exalted. 

In early age, Hazrat Ibraheem Alaihis Salaam lived in Iraq and married Hazrat Sarah Radhiallahu Anha who embraced Islam at the early age. She was a wealthy woman and possessed many lands and a lot of animals which she eventually gave to Ibrahim Alaihis Salaam to look after. When Hazrat Ibraheem Alaihis Salaam was blessed with prophethood, he begun calling and inviting his nation towards Deen; but they did not pay heed to him and refuted the message that he had brought. Thereafter, Hazrat Ibraheem Alaihis Salaam migrated from there to Palestine with his wife Sarah Radhiallahu Anha and nephew Hazrat Loot Alaihis Salaam and preached and invited people of that locality who were idol and star worshippers.
