Who was the first child to accept Islam?

1. Hazrat Zainab (RA)
2. Hazrat Ali (RA)
3. Hazrat Hasan (RA)
4. Hazrat Hussain (RA)

Hazrat Ali (RA), the Prophet’s cousin and son-in-law, was the first child to accept Islam at age 10. Raised in the Prophet’s household, he displayed unmatched bravery in defending Islam. He later became the fourth caliph and a central figure in Islamic history. His scholarly contributions, including the compilation of Nahj al-Balagha, remain influential in theology and jurisprudence.
