﴿ فَلَمَّا رَءَآ أَيْدِيَهُمْ لَا تَصِلُ إِلَيْهِ نَكِرَهُمْ وَأَوْجَسَ مِنْهُمْ خِيفَةًۭ ۚ قَالُوا۟ لَا تَخَفْ إِنَّآ أُرْسِلْنَآ إِلَىٰ قَوْمِ لُوطٍۢ ﴾

“But when he saw that their hands did not reach out towards it, he deemed their conduct strange and became apprehensive of them. [But] they said: "Fear not! Behold, we are sent to the people of Lot.”

Literally ‘their hands did not reach towards the meal’.
