Once a tumbler (full of milk or water) was brought to Messenger of Allah ﷺ who drank from it, while on his right side there was sitting a boy who was the youngest of those who were present, and on his left side there were old men. The Prophet ﷺ asked, "O boy ! Do you allow me to give (the drink) to the elder people (first)?" The boy said, "I will not prefer anybody to have my share from you, O Allah's Apostle!" So, he gave it to the boy.  

أُتِيَ رَسُولُ اللَّهِ ﷺ بِقَدَحٍ فَشَرِبَ وَعَنْ يَمِينِهِ غُلاَمٌ هُوَ أَحْدَثُ الْقَوْمِ وَالأَشْيَاخُ عَنْ يَسَارِهِ قَالَ يَا غُلاَمُ أَتَأْذَنُ لِي أَنْ أُعْطِيَ الأَشْيَاخَ فَقَالَ مَا كُنْتُ لأُوثِرَ بِنَصِيبِي مِنْكَ أَحَدًا يَا رَسُولَ اللَّهِ فَأَعْطَاهُ إِيَّاهُ  

The Prophet ﷺ said, "By Him in Whose Hands my soul is, I will drive some people out from my (sacred) Fount on the Day of Resurrection as strange camels are expelled from a private trough."  

عَنِ النَّبِيِّ ﷺ قَالَ وَالَّذِي نَفْسِي بِيَدِهِ لأَذُودَنَّ رِجَالاً عَنْ حَوْضِي كَمَا تُذَادُ الْغَرِيبَةُ مِنَ الإِبِلِ عَنِ الْحَوْضِ  

The Prophet ﷺ said, "May Allah be merciful to the mother of Ishmael! If she had left the water of Zamzam (fountain) as it was, (without constructing a basin for keeping the water), (or said, "If she had not taken handfuls of its water"), it would have been a flowing stream. Jurhum (an Arab tribe) came and asked her, 'May we settle at your dwelling?' She said, 'Yes, but you have no right to possess the water.' They agreed."  

قَالَ النَّبِيُّ ﷺ يَرْحَمُ اللَّهُ أُمَّ إِسْمَاعِيلَ لَوْ تَرَكَتْ زَمْزَمَ أَوْ قَالَ لَوْ لَمْ تَغْرِفْ مِنَ الْمَاءِ لَكَانَتْ عَيْنًا مَعِينًا وَأَقْبَلَ جُرْهُمُ فَقَالُوا أَتَأْذَنِينَ أَنْ نَنْزِلَ عِنْدَكِ قَالَتْ نَعَمْ وَلاَ حَقَّ لَكُمْ فِي الْمَاءِ قَالُوا نَعَمْ  

The Prophet ﷺ said, "There are three types of people whom Allah will neither talk to, nor look at, on the Day of Resurrection. (They are): -1. A man who takes an oath falsely that he has been offered for his goods so much more than what he is given, -2. a man who takes a false oath after the ʿAsr prayer in order to grab a Muslim's property, and -3. a man who withholds his superfluous water. Allah will say to him, "Today I will withhold My Grace from you as you withheld the superfluity of what you had not created."  

عَنِ النَّبِيِّ ﷺ قَالَ ثَلاَثَةٌ لاَ يُكَلِّمُهُمُ اللَّهُ يَوْمَ الْقِيَامَةِ وَلاَ يَنْظُرُ إِلَيْهِمْ رَجُلٌ حَلَفَ عَلَى سِلْعَةٍ لَقَدْ أَعْطَى بِهَا أَكْثَرَ مِمَّا أَعْطَى وَهْوَ كَاذِبٌ وَرَجُلٌ حَلَفَ عَلَى يَمِينٍ كَاذِبَةٍ بَعْدَ الْعَصْرِ لِيَقْتَطِعَ بِهَا مَالَ رَجُلٍ مُسْلِمٍ وَرَجُلٌ مَنَعَ فَضْلَ مَاءٍ فَيَقُولُ اللَّهُ الْيَوْمَ أَمْنَعُكَ فَضْلِي كَمَا مَنَعْتَ فَضْلَ مَا لَمْ تَعْمَلْ يَدَاكَ قَالَ عَلِيٌّ حَدَّثَنَا سُفْيَانُ غَيْرَ مَرَّةٍ عَنْ عَمْرٍو سَمِعَ أَبَا صَالِحٍ يَبْلُغُ بِهِ النَّبِيَّ ﷺ
