During this Ghazwah, the hypocrites almost managed to create a sort of discord among the Muslims themselves, coupled with a serious and ugly slander against the Prophet (Peace be upon him) himself. In short, their behaviour was an authentic translation of Allâh’s Words:
“Had they marched out with you, they would have added to you nothing except disorder, and they would have hurried about in your midst (spreading corruption) and sowing sedition among you …” [9:47]
A quarrel was about to break out between the Emigrants and the Helpers on account of plots and evil intentions designed by the hypocrites. The Prophet (Peace be upon him) told them off describing their misbehaviour as something smacking of pre-Islamic practices. They, hypocrites with ‘Abdullah bin ‘Ubai at their head, were furious for the challenge which the Muslims showed towards the hostile plans and vicious intrigues woven behind closed doors, and swore “the most honourable will expel the meanest out of Madinah,” and added: “They (the Muslims) have outnumbered and shared us our land. If you fatten your dog, it will eat you.” When that talk was reported to the Prophet (Peace be upon him), ‘Umar, a venerable Companion, asked for permission to have Ibn ‘Ubai killed. The Prophet (Peace be upon him) naturally turned down his proposal on the grounds that it did not become of a Prophet (Peace be upon him) to be accused of killing his people. He, on the contrary in an unexpected move, asked ‘Umar to announce departure. He marched with his men for two days until the sun grew too hot. They stopped and fell asleep, a clever attempt at diverting his people’s attention from the previous event. ‘Abdullah’s son heard of that vile of his father and as the party reached Madinah, he drew his sword and barred his father’s entry into the town until he had confessed and declared that he himself was the meanest of the citizens of Madinah and the Prophet (Peace be upon him) the most honourable of them. Thus the boast recoiled on his head. It was also reported that the son was ready to kill his father if the Prophet (Peace be upon him) had wanted him to.
