Allah said,

﴿وَيُكَلِّمُ النَّاسَ فِى الْمَهْدِ وَكَهْلاً﴾

(He will speak to the people, in the cradle and in manhood,) calling to the worship of Allah Alone without partners, while still in the cradle, as a miracle from Allah, and when he is a man, by Allah's revelation to him.

Muhammad bin Ishaq recorded that Abu Hurayrah said that the Messenger of Allah said,

«مَا تَكَلَّمَ مَوْلُودٌ فِي صِغَرِهِ إِلَّا عِيسَى وَصَاحِبُ جُرَيْج»

(No infant spoke in the cradle except `Isa and the companion of Jurayj.)

Ibn Abi Hatim recorded that Abu Hurayrah said that the Prophet said,

«لَمْ يَتَكَلَّمْ فِي الْمَهْدِ إِلَّا ثَلَاثَةٌ: عِيسَى، وَصَبِيٌّ كَانَ فِي زَمَنِ جُرَيْجٍ، وَصَبِيٌّ آخَر»

(No infant spoke in the cradle except three, `Isa, the boy during the time of Jurayj, and another boy.)

﴿وَمِنَ الصَّـلِحِينَ﴾

(And he will be one of the righteous.) in his statements and actions, for he will possess, pure knowledge and righteous works.
