Messenger of Allah 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 Messenger of Allah ﷺ ." Messenger of Allah ﷺ said, "Give me water to drink." Al-Abbas said, "O Messenger of Allah ﷺ! The people put their hands in it." Messenger of Allah 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. (Using translation from Bukhārī 1635)
أَنَّ رَسُولَ اللهِ ﷺ جَاءَ إِلَى السِّقَايَةِ فَاسْتَسْقَى فَقَالَ الْعَبَّاسُ يَا فَضْلُ اذْهَبْ إِلَى أُمِّكَ فَأْتِ رَسُولَ اللهِ ﷺ بِشَرَابٍ مِنْ عِنْدِهَا فَقَالَ اسْقِنِي فَقَالَ يَا رَسُولَ اللهِ إِنَّهُمْ يَجْعَلُونَ أَيْدِيَهُمْ فِيهِ قَالَ اسْقِنِي فَشَرِبَ مِنْهُ ثُمَّ أَتَى زَمْزَمَ وَهُمْ يَسْقُونَ وَيَعْمَلُونَ فِيهَا فَقَالَ اعْمَلُوا فَإِنَّكُمْ عَلَى عَمِلٍ صَالِحٍ ثُمَّ قَالَ لَوْلَا أَنْ تُغْلَبُوا لَنَزَلْتُ حَتَّى أَضَعَ الْحَبْلَ عَلَى هَذِهِ يَعْنِي عَاتِقَهُ وَأَشَارَ إِلَى عَاتِقِهِ
