75. This shows that the angels had come to Prophet Abraham (peace be upon him) in the form of human beings and had not disclosed their identity. Therefore he took them for strangers and brought a roasted calf for their entertainment.
76. Some commentators are of the view that Prophet Abraham (peace be upon him) was afraid of them because of their refusal to eat his meal. He had concluded that they had come to him with some evil intention. For, according to the Arab tradition, if some strangers refused hospitality, it meant that they had not come as guests but as enemies to plunder. But this view is not supported by the succeeding verse.
77. The wording of their answer shows that Prophet Abraham (peace be upon him) had understood from their refusal to eat that they were angels. But he was afraid of their visit because he knew that the coming of the angels in the human shape did not bode well: So he was fearful that they might have come to take them to task for some offense committed by the people of his household or of his habitation or by himself. Had it been the same thing that the commentators presumed, then their answer should have been, “Don’t fear us for we are angels from your Lord.” But the answer they gave to remove his fear, “Don’t have any fear for we have been sent to the people of Lot (and not to you),” shows that Prophet Abraham (peace be upon him) knew that they were angels but was troubled in his mind as to the reason of their visit in the human form. This was because the angels came in human form when some one was either to be put to a hard trial or punished severely for some offense.
78. It appears from this that the news of the visit of the angels in the human form had made the people of the house uneasy. So Prophet Abraham’s Prophet Abraham (peace be upon him) wife had also come there to know what the matter was. She laughed with joy when she learned that the angels were sent not to punish their people but the people of Lot (peace be upon him).
79. The angels told the good news of a son to Sarah instead of Prophet Abraham (peace be upon him) because he already had a son, Ismail from Hajirah but had no child from her. Therefore to remove her sorrow they told her the good news that a son, Isaac, will be born to her, who will have a son, Jacob, both of whom will be great Messengers of Allah.
80. These words were not used by her in their literal sense as an exclamation of grief and lamentation. She uttered these words merely to express surprise at the news.
81. According to the Bible Prophet Abraham (peace be upon him) was 100 years old at the time and Sarah was 90 years.
82. The question was posed to her to remind her that though people of old age do not bear children, it is not beyond Allah’s power to bring this about. Therefore a true believer like her should not show any surprise at the good news when it is conveyed to her from Allah.
