Quran 11:71 · Hud

Once when Abraham was about a hundred years old, several very handsome young men entered his house. Considering them as guests, he immediately arranged for their food. They were not human beings, but angels of God. They had come with the dual purpose of giving the good news of children to Abraham, and destroying Lot’s community, who had gone to the furthest extremes in their arrogance and rejection of the Truth. Conveying to Abraham and his wife the good news of Isaac (Ishaq), a son, and Jacob (Ya‘qub), a grandson, did not simply mean giving the good news of children in the usual sense. No, indeed, this amounted to the bringing into existence of a line of righteous and mission-oriented human beings. It is a matter of historical record that generally it is a ‘family’ that rises in the service of religion. The history of the prophets and the events in the lives of the true followers who came after them demonstrate this fact. This is because one to whom Truth is revealed is an ordinary person in the eyes of his contemporaries, and this makes it difficult for the common people to recognise his status and support him. But from within his own family, personal relationships become an additional force. What outsiders are unable to see—due to their love of externals—the family members clearly appreciate, thanks to the element of attachment. Not finding it difficult to understand his real position, they become supporters of his mission.
