Quran 25:7 Al-Furqan, ayah 7 of 77

وَقَالُوا۟ مَالِ هَـٰذَا ٱلرَّسُولِ يَأْكُلُ ٱلطَّعَامَ وَيَمْشِى فِى ٱلْأَسْوَاقِ ۙ لَوْلَآ أُنزِلَ إِلَيْهِ مَلَكٌ فَيَكُونَ مَعَهُۥ نَذِيرًا ۝٧

25:7 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.
