Al-Imām al-Bukhārī narrates: ‘Abdullāh ibn Munīr narrated to us; he heard from ‘Abdullāh ibn Bakr, who said: Ḥumayd narrated to us,
from Anas ibn Mālik (may Allāh Almighty be content with him), who said: The time for prayer came. Those whose homes were nearby stood up and went (to perform wuḍūʾ), while the rest remained there. Then a stone trough containing water was brought to the Messenger of Allāh ﷺ. It was so small that he could not fully spread his hand in it. Yet all the people performed wuḍūʾ from it. We asked, “How many of you were there?” He replied, “More than eighty.”
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُنِيرٍ، سَمِعَ عَبْدَ اللَّهِ بْنَ بَكْرٍ، قَالَ حَدَّثَنَا حُمَيْدٌ، عَنْ أَنَسٍ
قَالَ حَضَرَتِ الصَّلاَةُ، فَقَامَ مَنْ كَانَ قَرِيبَ الدَّارِ إِلَى أَهْلِهِ، وَبَقِيَ قَوْمٌ، فَأُتِيَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِمِخْضَبٍ مِنْ حِجَارَةٍ فِيهِ مَاءٌ، فَصَغُرَ الْمِخْضَبُ أَنْ يَبْسُطَ فِيهِ كَفَّهُ، فَتَوَضَّأَ الْقَوْمُ كُلُّهُمْ. قُلْنَا كَمْ كُنْتُمْ قَالَ ثَمَانِينَ وَزِيَادَةً.
