مَّا ٱلْمَسِيحُ ٱبْنُ مَرْيَمَ إِلَّا رَسُولٌۭ قَدْ خَلَتْ مِن قَبْلِهِ ٱلرُّسُلُ وَأُمُّهُۥ صِدِّيقَةٌۭ ۖ كَانَا يَأْكُلَانِ ٱلطَّعَامَ ۗ ٱنظُرْ كَيْفَ نُبَيِّنُ لَهُمُ ٱلْءَايَٰتِ ثُمَّ ٱنظُرْ أَنَّىٰ يُؤْفَكُونَ
The Messiah, son of Mary, was no other than a messenger, messengers (the like of whom) had passed away before him. And his mother was a saintly woman. And they both used to eat (earthly) food. See how We make the revelations clear for them, and see how they are turned away!
Surah Al-Maaida(5:75)
