I came to the Prophet (may Allah's peace and blessings be upon him) when he was in a red leather tent. Bilāl stepped out with ablution water (that was left over from the Prophet's ablution. There were some people who managed to get some of it (seeking its blessing), whereas others just received a sprinkle of it

عن أبي جُحَيْفَةَ وَهْبِ بْنِ عَبْدِ اللَّهِ السُّوَائِيِّ رضي الله عنه قال: «أَتَيتُ النَبِيَّ صلى الله عليه وسلم وهو في قُبَّةٍ لَهُ حَمرَاءَ مِن أَدَمٍ، قال: فَخَرَج بِلاَل بِوَضُوءٍ، فمن نَاضِحٍ ونَائِلٍ، قال: فَخَرَجَ النبِيَّ صلى الله عليه وسلم عليه حُلَّةٌ حَمرَاءُ، كَأَنِّي أَنظُرُ إلى بَيَاضِ سَاقَيهِ، قال: فَتَوَضَّأ وأَذَّن بِلاَل، قال: فَجَعَلَتُ أتَتَبَّعُ فَاهُ هَهُنَا وهَهُنَا، يقول يمِينا وشِمالا: حَيَّ على الصَّلاة؛ حيَّ عَلَى الفَلاَح. ثُمَّ رَكَزَت لَهُ عَنَزَةٌ، فَتَقَدَّمَ وصلى الظُهرَ رَكعَتَين، ثُمَّ لَم يَزلَ يُصِلِّي رَكعَتَين حَتَّى رَجَعَ إِلى المَدِينَة».

Abu Juhayfah Wahb ibn ‘Abdullāh As-Suwā'i (may Allah be pleased with him) reported: I came to the Prophet (may Allah's peace and blessings be upon him) when he was in a red leather tent. Bilāl stepped out with ablution water (that was left over from the Prophet's ablution). There were people who managed to get some of it (seeking its blessing), whereas others just received a sprinkle of it. Then the Prophet (may Allah's peace and blessings be upon him) came out wearing a red garment. It is as if I am looking right now at the whiteness of his legs. He performed ablution and Bilāl called the Adhān (the call to prayer). I kept watching the movement of his mouth (as he turned) to this side and that side and he said to the right and to the left: "Come to prayer, come to success!" Then a spear was fixed for him (in the ground). He stepped forward and performed two Rak‘ahs for the Zhuhr prayer, and he did not stop performing two Rak‘ahs until he returned to Madīnah.
