The reciter: Ishaq narrated to us, Khalid narrated to us, from Khalid al-Hadha, from Ikrimah, from Ibn Abbas (may Allah be pleased with them both):
Allah's Messenger (ﷺ) came to the drinking place and asked for water. Al-Abbas said, "O Fadl! Go to your mother and bring water from her for Allah's Messenger (ﷺ) ." Allah's Messenger (ﷺ) said, "Give me water to drink." Al-Abbas said, "O Allah's Messenger (ﷺ)! The people put their hands in it." Allah's Messenger (ﷺ) again said, 'Give me water to drink. So, he drank from that water and then went to the Zamzam (well) and there the people were offering water to the others and working at it (drawing water from the well). The Prophet (ﷺ) then said to them, "Carry on! You are doing a good deed." Then he said, "Were I not afraid that other people would compete with you (in drawing water from Zamzam), I would certainly take the rope and put it over this (i.e. his shoulder) (to draw water)." On saying that the Prophet (ﷺ) pointed to his shoulder.
أن رسول الله صلى الله عليه وسلم جاء إلى السقاية فاستسقى فقال العباس يا فضل اذهب إلى أمك فأت رسول الله صلى الله عليه وسلم 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 Sahih al-Bukhari 1635
