Abdullah bin Abbas reported,

The Messenger of Allah ﷺ came to the watering place and asked for a drink.Abbas said, "Fadl, go to your mother and bring the Messenger of Allah ﷺ a drink from her."The Prophet ﷺ said, "Give me a drink from here."Abbas said, "Messenger of Allah, the people put their hands in it!"He said again, "Give me a drink."So he drank from it. Then he came to Zamzam, where the people were drawing water and working at it, and he said, "Keep working, for you are engaged in a righteous work."Then he said, "Were it not that you would be overwhelmed, I would come down and place the rope on this," meaning his shoulder, and he pointed to his shoulder.

عن ابن عباس

أن رسول الله ﷺ جاء إلى السقاية فاستسقى، فقال العباس: يا فضل اذهب إلى أمك فأت رسول الله ﷺ بشراب من عندها فقال: اسقني. قال: يا رسول الله إنهم يجعلون أيديهم فيه! قال: اسقني. فشرب منه، ثم أتى زمزم وهم يسقون ويعملون فيها، فقال: اعملوا فإنكم على عمل صالح. ثم قال: لولا أن تغلبوا لنزلت حتى أضع الحبل على هذه يعني عاتقه وأشار إلى عاتقه.
