The Coming of the Angels to Ibrahim and Their Glad Tidings to Him of Ishaq and Ya`qub
Allah, the Exalted, says,
وَلَقَدْ جَآءَتْ رُسُلُنَآ
(And verily, there came Our messengers) The word "messengers" here means angels.
إِبْرَهِيمَ بِالْبُشْرَى
(to Ibrahim with the glad tidings.) It has been said that the word "the glad tidings" means, "Receive the glad tidings of Ishaq." Others have said that it means, "The destruction of the people of Prophet Lut." The proof of the correctness of the first view is in Allah's statement,
(Then when the fear had gone away from (the mind of) Ibrahim, and the glad tidings had reached him, he began to plead with Us for the people of Lut.)11:74
In verse 70, it was said: فَلَمَّا رَأَىٰ أَيْدِيَهُمْ لَا تَصِلُ إِلَيْهِ نَكِرَهُمْ (So, when he noticed their hands not reaching for it, he found them strange and felt a bit of fright from them).
From here we learn that there are rules of etiquette for guests as well. A guest should accept whatever is offered. Let him partake from it a little bit to please the host, even if not willing to eat because of unfavorable taste or apprehended harm.
This very sentence also tells us that the host should not consider himself absolved after having placed the food before the guest. In-stead, he should be benignly watching whether or not the guest is par-taking of the food, as was done by Sayyidna Ibrahim when he noticed that the angels were not eating.
