Sunan Ibn Majah, Volume 3, Book 16, Hadith 2448 (DarusSalam) ⓘ

It was narrated that Abu Hurairah said: “A man from among the Ansar Came and said: 'O Messenger of Allah, why do I see that your color has changed?' He said: 'Hunger.' So the Ansari went to his dwelling, but he did not find anything in his dwelling, so he went out looking, and he found a Jew watering his date-palm trees. The Ansari stipulated that he would not take any dates that were black (rotten), hard and dried out or inferior, and he would only take good quality dates. He earned nearly two Sa's (of dates), and he brought it to the Prophet.”

حَدَّثَنَا عَلِيُّ بْنُ الْمُنْذِرِ، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعِيدٍ، عَنْ جَدِّهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ جَاءَ رَجُلٌ مِنَ الأَنْصَارِ فَقَالَ يَا رَسُولَ اللَّهِ مَا لِي أَرَى لَوْنَكَ مُنْكَفِئًا ‏.‏ قَالَ ‏ "‏ الْخَمْصُ ‏" ‏ ‏.‏ فَانْطَلَقَ الأَنْصَارِيُّ إِلَى رَحْلِهِ فَلَمْ يَجِدْ فِي رَحْلِهِ شَيْئًا فَخَرَجَ يَطْلُبُ فَإِذَا هُوَ بِيَهُودِيٍّ يَسْقِي نَخْلاً فَقَالَ الأَنْصَارِيُّ لِلْيَهُودِيِّ أَسْقِي نَخْلَكَ قَالَ نَعَمْ ‏.‏ قَالَ كُلُّ دَلْوٍ بِتَمْرَةٍ ‏.‏ وَاشْتَرَطَ الأَنْصَارِيُّ أَنْ لاَ يَأْخُذَ خَدِرَةً وَلاَ تَارِزَةً وَلاَ حَشَفَةً وَلاَ يَأْخُذَ إِلاَّ جَلْدَةً ‏.‏ فَاسْتَقَى بِنَحْوٍ مِنْ صَاعَيْنِ فَجَاءَ بِهِ إِلَى النَّبِيِّ صلى الله عليه وسلم ‏.‏
