When the child begins to talk

Recite the following Ayah of the Qur'an first:

وَقُلِ الْحَمْدُ لِلَّهِ الَّذِي لَمْ يَتَّخِذْ وَلَدَاً وَلَمْ يَكُنْ لَهُ شَرِيكٌ فِي الْمُلْكِ وَلَمْ يَكُنْ لَهُ وَلِيٌّ مِنَ الذُّلِّ وَكَبِّرْهُ تَكْبِيرَاً

"Praise to Allah , who has not taken a son and has had no partner in [His] dominion and has no [need of a] protector out of weakness; and glorify Him with [great] glorification.". (QS 17:111)

and then:

لَا إِلَهَ إِلَّا اللَّهُ

"There is no god, except Allah"

He Perfected Your Forms

He has created the heavens and the earth in just proportions, and has given you shape, and made your shapes beautiful: and to Him is the final Goal. He knows what is in the heavens and on earth; and He knows what ye conceal and what ye reveal: yea, Allah knows well the (secrets) of (all) hearts. (QS 64:3-4)

From Allah, verily nothing is hidden on earth or in the heavens. He it is Who shapes you in the wombs as He pleases. There is no god but He, the Exalted in Might, the Wise. (QS 3:5-6)
