Sahih al-Bukhari 2358
Narrated Abu Huraira:
Allah's Messenger (ﷺ) said, "There are three persons whom Allah will not look at on the Day of 
Resurrection, nor will he purify them and theirs shall be a severe punishment. They are: 
-1. A man possessed superfluous water, on a way and he withheld it from travelers. 
-2. A man who gave a pledge of allegiance to a ruler and he gave it only for worldly benefits. If the 
ruler gives him something he gets satisfied, and if the ruler withholds something from him, he gets 
dissatisfied. 
-3. And man displayed his goods for sale after the `Asr prayer and he said, 'By Allah, except Whom 
None has the right to be worshipped, I have been given so much for my goods,' and somebody 
believes him (and buys them). 
The Prophet (ﷺ) then recited: "Verily! Those who purchase a little gain at the cost of Allah's Covenant and 
their oaths." (3.77)
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا عَبْدُ الْوَاحِدِ بْنُ زِيَادٍ، عَنِ الأَعْمَشِ، قَالَ سَمِعْتُ أَبَا صَالِحٍ، يَقُولُ سَمِعْتُ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ ثَلاَثَةٌ لاَ يَنْظُرُ اللَّهُ إِلَيْهِمْ يَوْمَ الْقِيَامَةِ، وَلاَ يُزَكِّيهِمْ، وَلَهُمْ عَذَابٌ أَلِيمٌ رَجُلٌ كَانَ لَهُ فَضْلُ مَاءٍ بِالطَّرِيقِ، فَمَنَعَهُ مِنِ ابْنِ السَّبِيلِ، وَرَجُلٌ بَايَعَ إِمَامًا لاَ يُبَايِعُهُ إِلاَّ لِدُنْيَا، فَإِنْ أَعْطَاهُ مِنْهَا رَضِيَ، وَإِنْ لَمْ يُعْطِهِ مِنْهَا سَخِطَ، وَرَجُلٌ أَقَامَ سِلْعَتَهُ بَعْدَ الْعَصْرِ، فَقَالَ وَاللَّهِ الَّذِي لاَ إِلَهَ غَيْرُهُ لَقَدْ أَعْطَيْتُ بِهَا كَذَا وَكَذَا، فَصَدَّقَهُ رَجُلٌ‏"‏ ثُمَّ قَرَأَ هَذِهِ الآيَةَ ‏{‏إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلاً‏}‏
