Al-Mukhtasar fi Tafsir
When they did not eat, he concealed his fear of them, but they understood this and said to him to put him at ease: “Do not fear. We are messengers from Allah”. And they informed him of what will please him, i.e., that he will have a son who will have a lot of knowledge. The one regarding whom glad tidings were given was Isaac (peace be upon him).
