Thus Allah made things easier for Maryam and provided the true explanation to the people through the words of Jesus (as). With such a miracle, the disbelief of the people surrounding Maryam simply failed.
She pointed towards him. They said, "How can a baby in the cradle speak?" He said, "I am the slave of Allah. He has given me the Book and made me a Prophet. He has made me blessed wherever I am and directed me to do prayer and pay poor-due as long as I live, and to show devotion to my mother. He has not made me insolent or arrogant. Peace be upon me the day I was born, and the day I die and the day I am raised up again alive." (Surah Maryam: 29-33)
No doubt, a baby speaking fluently in his cradle is a great miracle. The people of Maryam were astonished on hearing these words of wisdom from a baby in the cradle and this occasion proved to them that his birth was a miracle. All these miraculous incidents showed that the baby in the cradle was a messenger of Allah.
This is the relief Allah provided Maryam in return for the trust she placed in Him. By showing such an astounding miracle, she responded to the slanders against her. Yet, Allah informs us that a grievous disaster awaited those who did not dismiss their bad thoughts about Maryam despite this miracle:
And on account of their disbelief and their utterance of a monstrous slander against Maryam. (Surat an-Nisa: 156)
