Falamma raa aydiyahum la tasilu ilayhi nakirahum waawjasa minhum kheefatan qaloo la (surah Hud: 70)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(11:70) When he perceived that their hands could not reach it, he mistrusted them, and felt afraid of them. *76 They said: 'Do not be afraid. We have been sent to the people of Lot. *77

Falammaa ra aaa aidiyahum laa tasilu ilaihi nakirahum wa awjasa minhum kheefah; qaaloo la takhaf innaaa ursilnaaa ilaa qawmi Loot

*76). Some commentators on the Qur'an are of the view that when the guests hesitated to take food Prophet Abraham (peace be on him) felt suspicious about their intentions. He even became apprehensive that they had come with some hostile design. For, in Arabia when someone declines the food offered to him by way of hospitality, this gives rise to the fear that he has not come as a guest but rather with subversive purposes. The very next verse, however, does not lend any support to this view.
*77). The words as well as the tone of the verse suggest that as soon as Abraham (peace be on him) noticed that his guests were disinclined to eat, he realized that they were angels. Since angels appear in human form only in very exceptional circumstances, what terrified Abraham (peace be on him) was the possibility that the angels may have been sent to inflict punishment on account of any lapses that he himself, his family, or his people may have committed. Had Abraham (peace be on him) not been sure about the identity of his guests - as some Qur'an-commentators believe - they would have said: 'Do not fear, we are angels sent by your Lord.' However, they did not say so. They rather tried to allay Abraham's fears by saying: 'Do not be afraid, we have been sent to the people of Lot.' It is, thus, clear that Abraham had become aware of their true identity. What caused Abraham (peace be on him) to worry was the idea that the angels had been sent to his people, that his people were about to suffer a severe chastisement. However, he was soon to feel relieved that the angels had been sent to the people of Lot rather than to his own. So there was no reason to fear that his own people would soon suffer destruction.
