We were with the Prophet ﷺ and the people could not find water. A vessel was brought, and he placed his hand into it. I saw water gushing from between his fingers, while he said, "Come to purification, and blessing is from Allah ."Amash said, Salim bin Abu Jaad related to me, he said, I asked Jabir, "How many of you were there that day?"He replied, "One thousand five hundred."
أخبرنا إسحق بن إبراهيم قال أنبأنا عبد الرزاق قال أنبأنا سفيان عن الأعمش عن إبراهيم عن علقمة
كنا مع النبي ﷺ فلم يجدوا ماء فأتي بتور فأدخل يده فلقد رأيت الماء يتفجر من بين أصابعه ويقول حي على الطهور والبركة من الله عز وجل قال الأعمش فحدثني سالم بن أبي الجعد قال قلت لجابر كم كنتم يومئذ قال ألف وخمس مائة
