About Abu Bakr:
Abdullah ibn Abi Quhaafah was a senior companion (Sahabi) and the father-in-law of the Islamic prophet Muhammad. He ruled over the Rashidun Caliphate from 632 to 634 CE, when he became the first Muslim Caliph following Muhammad's death. As caliph, Abu Bakr succeeded to the political and administrative functions previously exercised by Muhammad. He was also commonly known as The Truthful (Arabic: ??????? Al-Siddiq).
Follow the way of life, which the Holy Prophet has shown you, for verily that is the right path.
Abu BakrTo fight against the infidels is Jihad; but to fight against your evil self is greater Jihad.
Abu Bakr
