Overall meaning :
Has the story of Abraham’s honoured angel guests reached you, Muhammad? They entered upon him and greeted him, saying, ‘Peace be with you!’ ‘Peace be with you! You are unknown to me,’ he replied. Then he slipped off to his family and returned with a fat roasted calf, deeming them human beings. He placed it before them and, seeing that they did not touch it, he asked them, ‘Will you not eat?’
When they did not eat, he grew afraid of them, but they reassuringly said, ‘Have no fear,’ and they gave him the good news of the birth of a knowledgeable son (Isaac, peace be upon him). Whereupon his wife came forward with a loud cry when she overheard the good news and, striking her face in astonishment, said, ‘I am a barren old woman. How can I possibly conceive?’ ‘Thus has your Lord said,’ the angels replied. ‘He surely is the All-Wise, the All-knowing.’
