Glad tidings of Ishaaq AS 
In the meantime, three angels descended to the earth: Jibra`eel, Israfeel and Mikhaeel AS. They came in human shape and saluted Ibrahim AS. Ibrahim AS arose and welcomed them. He took them inside his tent, thinking they were strangers and guests. He seated them and made sure that they were comfortable, then excused himself to go to his people.

His wife Sarah arose when he entered. She had become old and white-haired.

Ibrahim AS said to her: “We have three strangers in the house.” “Who are they?” she asked. “I do not know any of them,” he answered. “What food have we got?” Ibrahim AS asked. “Half a sheep,” she replied. “Half a sheep! Slaughter a fat calf for them; they are strangers and guests,” he ordered while leaving.

The servants roasted and served a calf. Ibrahim AS invited the angels to eat, and he started eating so as to encourage them. He continued, but when he glanced at his guests to assure they were eating, he noticed that none of them had touched the food. He said to them: “Are you not going to eat?” He resumed eating, but when he glanced at them again he found that they were still not eating. Their hands did not reach out for the food. He began to fear them.

Ibrahim AS’s fears increased. The angels AS, however, were reading his inner thoughts and one of them said: “Do not fear.” Ibrahim AS raised his head and replied: “Indeed, I am in fear. I have asked you to eat food, but you do not stretch out your hands to eat. Do you intend me evil?”

One of the angels AS smiled and said: “We do not eat. We are Allah’s angels.” One of them then turned towards his wife and conveyed the glad tidings about Ishaaq.

Almighty Allah revealed:
وَلَقَدْ جَآءَتْ رُسُلُنَآ إِبْرَٰهِيمَ بِٱلْبُشْرَىٰ قَالُوا۟ سَلَـٰمًا ۖ قَالَ سَلَـٰمٌ ۖ فَمَا لَبِثَ أَن جَآءَ بِعِجْلٍ حَنِيذٍ
And verily, there came Our Messengers to Ibrahim with glad tidings. They said: “Salaam (greetings or peace)!” He answered: “Salaam (greetings or peace)” and he hastened to entertain them with a roasted calf.

فَلَمَّا رَءَآ أَيْدِيَهُمْ لَا تَصِلُ إِلَيْهِ نَكِرَهُمْ وَأَوْجَسَ مِنْهُمْ خِيفَةً ۚ قَالُوا۟ لَا تَخَفْ إِنَّآ أُرْسِلْنَآ إِلَىٰ قَوْمِ لُوطٍ
But when he saw their hands went not towards it (the meal), he felt some mistrust of them, and conceived a fear of them. They said: “Fear not, we have been sent against the people of Lot.”

وَٱمْرَأَتُهُۥ قَآئِمَةٌ فَضَحِكَتْ فَبَشَّرْنَـٰهَا بِإِسْحَـٰقَ وَمِن وَرَآءِ إِسْحَـٰقَ يَعْقُوبَ
And his wife was standing (there), and she laughed. But We gave her glad tidings of Ishaaq, and after him, of Yaqoob.
قَالَتْ يَـٰوَيْلَتَىٰٓ ءَأَلِدُ وَأَنَا۠ عَجُوزٌ وَهَـٰذَا بَعْلِى شَيْخًا ۖ إِنَّ هَـٰذَا لَشَىْءٌ عَجِيبٌ

She said (in astonishment): “Woe unto me! Shall I bear a child while I am an old woman, and here is my husband, an old man? Verily! This is a strange thing!”

قَالُوٓا۟ أَتَعْجَبِينَ مِنْ أَمْرِ ٱللَّهِ ۖ رَحْمَتُ ٱللَّهِ وَبَرَكَـٰتُهُۥ عَلَيْكُمْ أَهْلَ ٱلْبَيْتِ ۚ إِنَّهُۥ حَمِيدٌ مَّجِيدٌ
They said: “Do you wonder at the Decree of Allah? The Mercy of Allah and His Blessings be on you, O the family (of Ibrahim). Surely, He (Allah) is All-Praiseworthy, All-Glorious.” [Hud 11: 69-73]

Lesson to Learn:
Look at how quick Ibrahim AS was to entertain his guests. He didn’t even know who they were and nor did his wife, but immediately a calf was roasted and served. Let us then reflect on our treatment of our family when they visit and if they visit – the minute we see them pulling up into the driveway, we already looking for every excuse to get away, as if they are the cops and we are some robbers, but maybe we are robbers – we robbing ourselves of great reward by not being courteous and hospitable to them.
