Zubair Ibn Al-Awwam
He was related to both the Prophet (pbuh) and his wife Khadijah. His best friend was Talhah Ibn Ubaidullah. They both accepted Islam on the same day, and they both died on the same day.
He accepted Islam at the age of 15 and was one of the first seven people to believe in the Prophet’s message.
His wife was Asmah, the daughter of Abu Bakr and the sister of Aishah, who was also the wife of the Messenger of Allah. His son, Abdullah Ibn Zubair, would later lead a revolt against the Umayyah Dynasty.
He joined sides with Aishah against Ali ibn Abi Talib in the Battle of the Camel. Though he did not take part directly in the fighting, he was killed by one of Ali’s soldiers.
Abdur Rahman Ibn Awf
He was born during the Year of the Elephant and was the same age as the Messenger of Allah (pbuh). He accepted Islam at the hands of Abu Bakr.
Abdur Rahman Ibn Awf was known as one of the wealthiest companions. Still, he devoted muchof his time to worshiping Allah and defending Islam.
He was among those chosen by Umar Ibn Al-Khattab to succeed as the Caliph. However, Abdur Rahman recused himself and ultimately was the deciding factor in choosing Uthman over Ali.
He died three years before the beginning of the Muslim civil wars.
Sa’ad Ibn Abi Waqqas
He accepted Islam at the age of 13 and was probably the third or fourth person to do so. His family, especially his mother, pressured him to leave Islam. However, he held fast to his faith.
He fought alongside the Messenger of Allah (pbuh) in all of the major battles. He was known to be an excellent archer.
During the Caliphate of Umar he was the governor of Persia.
Unlike Talhah and Zubair, Sa’ad Ibn Abi Waqqas did not choose sides during the civil war against Ali. He refused to take part at all.
He died around eighty years of age during the Caliphate of Muawiyyah ibn Abi Sufyan.
Sa’eed Ibn Zaid
His father Zaid belonged to a monotheistic sect of Arabs that existed before Islam. Thus, Sa’eed Ibn Zaid never worshiped idols.
He was a cousin of Umar Ibn Al-Khattab and even married his sister Fatimah Bint Al-Khattab. Sa’eed and Fatimah were the 27th and 28th to accept Islam.
He fought under the leadership of Khalid Ibn Waleed during the Wars of Apostasy.
When Umar was nearing death, Sa’eed Ibn Zaid was not included in the list of potential successors due to his relationship with Umar. Umar did not want to turn the Caliphate into a dynasty.
Sa’eed Ibn Zaid died around 80 years of age.
Abu Ubaidah Ibn Al-Jarrah
He was probably the ninth person to accept Islam. Like many of the others, he also accepted Islam at the hands of Abu Bakr.
Abu Ubaidah’s mother was Muslim but his father was not. Due to the persecution of Muslims in Mecca, he moved to Abyssinia. However, when the Prophet ordered the Muslims to make the Hijrah (migration) to Medina, he did the same.
During the Battle of Uhud, the Prophet (pbuh) was injured by the Quraish. Abu Ubaidah pulled fragments of metal from the Prophet’s face with his teeth. In doing so, he also pulled out two of his own teeth.
When Umar succeeded Abu Bakr as the Caliph, he removed Khalid Ibn Waleed from the position of general of the Muslim armies. Umar appointed Abu Ubaidah Ibn Al-Jarrah in his stead.
Abu Ubaidah died while campaigning in the Levant in what is now modern-day Jordan. He was 58 years of age.
