"When the Messenger of Allah (ﷺ) died, some of the 'Arabs apostatized. 'Umar said: 'O Abu Bakr, how can you fight the 'Arabs? Abu Bakr said: 'The Messenger of Allah (ﷺ) said: I have been commanded to fight the people until they testify that La ilaha illallah (there is none worthy of worship except Allah) and that I am the Messenger of Allah, and establish prayer and pay Zakah?' By Allah, if they withhold from me a small she-goat that they used to give to the Messenger of Allah (ﷺ) I will fight them for withholding it.' ('Umar siad) 'By Allah, when I realized that (Abu) Bakr was confident about this idea, then I knew that this was teh truth.'" Abu 'Abdur-Rahman (An-Nasa'i) said: 'Imran Al Qattan is not strong in Hadith, and this narration is a mistake. The one that is before it is the correct narration of Az-Zuhri, from 'Ubaidullah bin 'Abdullah bin 'Utbah, from Abu Hurairah.
