﴿ فَأَشَارَتْ إِلَيْهِ ۖ قَالُوا۟ كَيْفَ نُكَلِّمُ مَن كَانَ فِى ٱلْمَهْدِ صَبِيًّۭا ﴾

“Thereupon she pointed to him. They exclaimed: "How can we talk to one who [as yet] is a little boy in the cradle?"”

In spite of Mary’s pointing toward the child, the people could not understand how they were supposed to talk to a small child. At that time, the child himself started speaking. In his miraculous utterances, there was, on the one hand, complete absolution of Mary and, on the other, advance evidence of his prophethood, so that when he grew up and declared his prophethood, there should be no scope for any doubt about it.
