Examples of Seriousness and Determination Among the Companions
1. The Seriousness and Firmness of Abu Bakr (may Allah be pleased with him) toward the Apostates and Those Who Withheld Zakah
Narrated Abu Hurairah (may Allah be pleased with him):
When the Prophet ﷺ passed away and Abu Bakr was appointed as Caliph, and some of the Arabs committed apostasy, Umar said: “O Abu Bakr! How can you fight the people when the Messenger of Allah ﷺ said: ‘I have been commanded to fight the people until they say: La ilaha illa Allah (There is no god but Allah).
Whoever says La ilaha illa Allah has protected his wealth and his life from me except by its right, and his account is with Allah.
Abu Bakr said: “By Allah! I will fight whoever differentiates between prayer and zakah, for zakah is the right of wealth. By Allah! If they withhold even a young she-goat which they used to give to the Messenger of Allah ﷺ, I will fight them for withholding it.”
“Abu Dharr said: “By the One in whose hand is my soul, I will proclaim it openly among them.” He went to the mosque and shouted at the top of his voice: “I bear witness that there is no god but Allah and that Muhammad is the Messenger of Allah.”
