Abu Bakr Al-Siddiq, Abdullah ibn Uthman Al-Taymi Al-Qurashi (50 BH–13 AH / 573–634 CE), was the first of the Rightly Guided Caliphs and one of the ten promised Paradise. He was an adviser and companion of the Prophet Muhammad and accompanied him during the migration to Medina. Sunni Muslims regard him as the best person after the prophets and messengers, the most faithful and ascetic of the companions, and the person most beloved by Muhammad after his wife Aisha. His name is usually followed by Al-Siddiq, a title Muhammad gave him for consistently affirming his truthfulness.
Abu Bakr was born in Mecca in 573 CE, two years and six months after the Year of the Elephant. [1][2] He was among the wealthy Quraysh before Islam. When Muhammad invited him to Islam, he accepted without hesitation and became the first free adult man to do so. He accompanied Muhammad from Mecca to Medina, participated in Badr and all the Prophet’s campaigns, and was instructed to lead prayers during Muhammad’s final illness.
Muhammad died on Monday, 12 Rabi Al-Awwal 11 AH, and Abu Bakr received allegiance as caliph the same day. He began administering the Islamic state, appointing governors and judges and dispatching armies. When many Arab tribes renounced Islam, he fought them and sent armies until the Arabian Peninsula was brought under Islamic rule. After the Ridda wars, he directed Muslim armies toward Iraq and the Levant, conquering most of Iraq and a large part of the Levant. Abu Bakr died on Monday, 22 Jumada Al-Akhirah 13 AH, aged 63, and was succeeded by Umar ibn Al-Khattab.
