It was narrated that 'Ali said: “I used to draw water, one bucket for a date, and I stipulated that they should be good quality, dried dates.”
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي إِسْحَاقَ، عَنْ أَبِي حَيَّةَ، عَنْ عَلِيٍّ، قَالَ كُنْتُ أَدْلُو الدَّلْوَ بِتَمْرَةٍ وَأَشْتَرِطُ أَنَّهَا جَلْدَةٌ .
