AbdusSalam ibn AbuHazim AbuTalut said:

I saw AbuBarzah who came to visit Ubaydullah ibn Ziyad. Then a man named Muslim who was there in the company mentioned it to me.

When Ubaydullah saw him, he said: This Muhammad of yours is a dwarf and fat. The old man (i.e. AbuBarzah) understood it.

So he said: I did not think that I should remain among people who would make me feel ashamed of the company of Muhammad ﷺ.

Thereupon Ubaydullah said: The company of Muhammad ﷺ is a honour for you, not a disgrace. He added: I called for you to ask about the reservoir. Did you hear the Messenger of Allah ﷺ mentioning anything about it? AbuBarzah said: Yes, not once, twice, thrice, four times or five times. If anyone believes it, may Allah not supply him with water from it. He then went away angrily.

حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا عَبْدُ السَّلاَمِ بْنُ أَبِي حَازِمٍ أَبُو طَالُوتَ، قَالَ شَهِدْتُ أَبَا بَرْزَةَ دَخَلَ عَلَى عُبَيْدِ اللَّهِ بْنِ زِيَادٍ فَحَدَّثَنِي فُلاَنٌ، سَمَّاهُ مُسْلِمٌ وَكَانَ فِي السِّمَاطِ فَلَمَّا رَآهُ عُبَيْدُ اللَّهِ قَالَ : إِنَّ مُحَمَّدِيَّكُمْ هَذَا الدَّحْدَاحُ، فَفَهِمَهَا الشَّيْخُ فَقَالَ مَا كُنْتُ أَحْسِبُ أَنِّي أَبْقَى فِي قَوْمٍ يُعَيِّرُونِي بِصُحْبَةِ مُحَمَّدٍ ﷺ فَقَالَ لَهُ عُبَيْدُ اللَّهِ إِنَّ صُحْبَةَ مُحَمَّدٍ ﷺ لَكَ زَيْنٌ غَيْرُ شَيْنٍ ثُمَّ قَالَ : إِنَّمَا بُعِثْتُ إِلَيْكَ لأَسْأَلَكَ عَنِ الْحَوْضِ سَمِعْتَ رَسُولَ اللَّهِ ﷺ يَذْكُرُ فِيهِ شَيْئًا فَقَالَ أَبُو بَرْزَةَ : نَعَمْ لاَ مَرَّةً وَلاَ ثِنْتَيْنِ وَلاَ ثَلاَثًا وَلاَ أَرْبَعًا وَلاَ خَمْسًا، فَمَنْ كَذَّبَ بِهِ فَلاَ سَقَاهُ اللَّهُ مِنْهُ ثُمَّ خَرَجَ مُغْضَبًا .
