Hadith: We set out with the Messenger of Allah (may Allah's peace and blessings be upon him) on one of his travels, and on the way the provisions became very scarce

عن زيد بن أَرْقَم رضي الله عنه قال: خَرَجْنَا مع رسول الله صلى الله عليه وسلم في سَفَر أَصَاب الناس فيه شِدَّة، فقال عبد الله بن أُبَيٍّ: لاَ تُنْفِقُوا على من عِندَ رسول الله صلى الله عليه وسلم حتى يَنْفَضُّوا، وقال: لَئِنْ رَجَعْنَا إلى المدينة لَيُخْرِجَنَّ الأَعَزُّ منها الأَذَلَّ، فَأَتَيْتُ رسول الله صلى الله عليه وسلم فَأَخْبَرْتُه بذلك، فأَرْسَل إلى عبد الله بن أُبي، فاجْتَهَدَ يَمِينَه: ما فعل، فقالوا: كَذَب زَيْدٌ رسول الله صلى الله عليه وسلم فَوَقَعَ في نَفْسِي ممَّا قَاَلُوه شِدَّة حتَّى أَنْزَل الله تعالى تَصْدِيقِي: (إذا جاءك المنافقون) ثم دعاهُم النبي صلى الله عليه وسلم لِيَسْتَغْفِرَ لهم فَلَوَّوْا رُؤُوسَهُم.

Zayd ibn Arqam (may Allah be pleased with him) reported: We set out with the Messenger of Allah (may Allah's peace and blessings be upon him) on one of his travels, and on the way the provisions became very scarce. ‘Abdullāh ibn Ubayy said: "Do not spend on those with the Messenger of Allah (may Allah's peace and blessings be upon him) until they disband." He also said: "If we return to Madīnah, surely the more honorable will expel therefrom the more humble." I went to the Messenger of Allah (may Allah's peace and blessings be upon him) and informed him of what he had said. So he sent for ‘Abdullāh ibn Ubayy, who denied it and swore that he did not say that. The people started saying: "Zayd lied to the Messenger of Allah (may Allah's peace and blessings be upon him)." I was hurt by what they said: until Allah, the Almighty, revealed that I had told the truth in the verses: {If the hypocrites come to you...} [Sūrat al-Munāfiqūn] Later, the Prophet (may Allah's peace and blessings be upon him) invited them (the hypocrites) to ask for forgiveness for them, but they turned their heads aside (in rejection)."
[Authentic hadith] - [Narrated by Bukhari & Muslim]

Explanation

What he meant by the more honorable was himself and his people, and by that Zayd ibn Arqam (may Allah be pleased with him) recounts that he was traveling with the Prophet (may Allah's peace and blessings be upon him) and there were believers and hypocrites with him. During the journey, the people were suffering severe distress due to a lack of provisions. ‘Abdullāh ibn Ubayy ibn Salūl (the head of disbelief and hypocrisy) spoke to the people, saying: {Do not spend on those with the Messenger of Allah until they disband} [Sūrat al-Munāfiqūn: 7]. What he meant was: do not give them any money, so they would suffer hunger and therefore disband and leave the Prophet (may Allah's peace and blessings be upon him). He also said: {If we return to Madīnah, surely the more honorable will expel therefrom the more humble} [Sūrat al-Munāfiqūn: 8], meaning the Messenger of Allah (may Allah's peace and blessings be upon him). When Zayd ibn Arqam heard what Ibn Salūl said: He went to the Prophet (may Allah's peace and blessings be upon him) and informed him of what ‘Abdullāh ibn Ubayy ibn Salūl had said to warn him of his evil. The Prophet (may Allah's peace and blessings be upon him) summoned Ibn Salūl, who swore emphatically that he had not said those things. This is the habit of the hypocrites; they can swear a false oath knowing that they are lying. The Prophet (may Allah's peace and blessings be upon him) used to accept their overt (deeds) and leave their covert (intentions) to Allah to judge. When Zayd ibn Arqam heard that Ibn Salūl had sworn that he had never made those statements, he was deeply distressed, because the man had sworn and taken an oath before the Messenger of Allah (may Allah's peace and blessings be upon him). The people said: "Zayd ibn Arqam lied to the Messenger of Allah (may Allah's peace and blessings be upon him)." However, soon Allah, the Almighty, exonerated Zayd and showed him to have been truthful through the verses of Sūrat al-Munāfiqūn. The Prophet (may Allah's peace and blessings be upon him) then invited the hypocrites and their chief, ‘Abdullāh ibn Ubayy, to ask Allah for forgiveness for them for the foul statements they had made. They rejected his invitation in arrogance and in contempt of the fact that the Prophet (may Allah's peace and blessings be upon him) was seeking forgiveness for them from Allah, the Almighty.
