Abd Allah ibn Umar ibn al-Khattab

ʿAbd Allāh ibn ʿUmar ibn al-Khaṭṭāb, commonly known as Ibn Umar, was a companion of the Islamic prophet Muhammad and a son of the second Caliph Umar. He was a prominent authority in hadith and law. He remained neutral during the events of the first Fitna (656–661). Muhammad's era — 610 to 632 Abd Allah ibn Umar (kunya Abu Abd al-Rahman ) was born in 610 in Mecca, three years after the beginning of Muhammad's message. He was the son of Umar ibn al-Khattab and Zaynab bint Maz'un. His full siblings were Hafsa and Abd al-Rahman. His paternal brothers, born to his stepmother Umm Kulthum bint Jarwal, were Zayd and Ubayd Allah. He had another stepmother, Qurayba bint Abi Umayya, but she had no children of her own. It was said that the young Abd Allah had vivid memories of his father's conversion to Islam. It is believed he accepted Islam together with his father, although some sources disagree about the year of his acceptance. He remembered following his father around the town as Umar declared his conversion to the neighbours and on the steps of the Kaaba. Abd Allah asserted, "Although I was very young at the time, I understood everything I saw." His mother Zaynab also became a Muslim, but his two stepmothers did not. His family emigrated to Medina in 622, although he may have emigrated to Medina before his father. Before the Battle of Uhud in March 625, Muhammad called Abd Allah Ibn Umar, who was then fourteen years old, to present himself. But when Abd Allah appeared, Muhammad would not allow him to fight in the battle. Two years later, as the Battle of the Trench approached, Muhammad again called Abd Allah, and this time he decreed that he was old enough because he was mature and reached puberty. He was also present at the Battle of Al-Muraysi in 628.
