Anas bin Malik reported,

The time for prayer arrived, so those whose homes were nearby went off to their families, while a group remained. A stone basin containing water was brought to the Messenger of Allah ﷺ, but the basin was too small for him to spread out his palm in it. Yet the entire group performed ablution from it.We asked, "How many of you were there?"He replied, "Eighty and more."

عن أنس قال

حضرت الصلاة فقام من كان قريب الدار إلى أهله وبقي قوم فأتي رسول الله ﷺ بمخضب من حجارة فيه ماء فصغر المخضب أن يبسط فيه كفه فتوضأ القوم كلهم قلنا كم كنتم قال ثمانين وزيادة
