وَقَالُوا۟ مَالِ هَٰذَا ٱلرَّسُولِ يَأْكُلُ ٱلطَّعَامَ وَيَمْشِى فِى ٱلْأَسْوَاقِ ۙ لَوْلَآ أُنزِلَ إِلَيْهِ مَلَكٌۭ فَيَكُونَ مَعَهُۥ نَذِيرًا
And they say: What aileth this messenger (of Allah) that he eateth food and walketh in the markets? Why is not an angel sent down unto him, to be a warner with him.
Surah Al-Furqaan(25:7)
