The Messenger of Allah ﷺ as saying: Excess water should not be withheld so as to prevent (cattle) by it from grass.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يُمْنَعُ فَضْلُ الْمَاءِ لِيُمْنَعَ بِهِ الْكَلأُ  

The Messenger of Allah ﷺ as saying: There are three people who Allah will not address on the Day of Judgement: a man who prevents traveller from the excess water which he has with him; and a man who swears for the goods (for sale) after the afternoon prayer, that is, (he swears) falsely; and a man who takes the oath of allegiance to a ruler (imam); if he gives him (something), he fullfils (the oath of allegiance) to him, if he does not give him (anything), he does not fulfill it.  

قَالَ رَسُولُ اللَّهِ ﷺ ثَلاَثَةٌ لاَ يُكَلِّمُهُمُ اللَّهُ يَوْمَ الْقِيَامَةِ رَجُلٌ مَنَعَ ابْنَ السَّبِيلِ فَضْلَ مَاءٍ عِنْدَهُ وَرَجُلٌ حَلَفَ عَلَى سِلْعَةٍ بَعْدَ الْعَصْرِ يَعْنِي كَاذِبًا وَرَجُلٌ بَايَعَ إِمَامًا فَإِنْ أَعْطَاهُ وَفَى لَهُ وَإِنْ لَمْ يُعْطِهِ لَمْ يَفِ لَهُ  

"He used: 'Not purify them ; grievously will be their penalty.'" He said about (selling) the goods: I swear by Allah, I was given (the price) so and so for it. The other man considered it to be correct and bought it.  

وَلاَ يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ وَقَالَ فِي السِّلْعَةِ بِاللَّهِ لَقَدْ أُعْطِيَ بِهَا كَذَا وَكَذَا فَصَدَّقَهُ الآخَرُ فَأَخَذَهَا  

On the authority of her father: My father asked the Prophet ﷺ for permission (to kiss his body). (When he was given permission), lifting his shirt he approached his body, and began to kiss and stick to him. He then asked: Prophet of Allah, what is the thing withholding of which is not lawful ? He replied: Water. He asked: Prophet of Allah, what is the thing withholding of which is not lawful ? He replied: Salt. He again asked: Prophet of Allah, what is the thing withholding of which is not lawful ? He said: That you do a good work is better for you.  

قَالَتِ اسْتَأْذَنَ أَبِي النَّبِيَّ ﷺ فَدَخَلَ بَيْنَهُ وَبَيْنَ قَمِيصِهِ فَجَعَلَ يُقَبِّلُ وَيَلْتَزِمُ ثُمَّ قَالَ يَا نَبِيَّ اللَّهِ مَا الشَّىْءُ الَّذِي لاَ يَحِلُّ مَنْعُهُ قَالَ الْمَاءُ قَالَ يَا نَبِيَّ اللَّهِ مَا الشَّىْءُ الَّذِي لاَ يَحِلُّ مَنْعُهُ قَالَ الْمِلْحُ قَالَ يَا نَبِيَّ اللَّهِ مَا الشَّىْءُ الَّذِي لاَ يَحِلُّ مَنْعُهُ قَالَ أَنْ تَفْعَلَ الْخَيْرَ خَيْرٌ لَكَ  

A man from the immigrants of the Companions of the Prophet ﷺ said: I participated in battle three times along with the Prophet ﷺ. I heard him say: Muslims have common share in three (things). grass, water and fire.  

عَنْ رَجُلٍ مِنَ الْمُهَاجِرِينَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ قَالَ غَزَوْتُ مَعَ النَّبِيِّ ﷺ ثَلاَثًا أَسْمَعُهُ يَقُولُ الْمُسْلِمُونَ شُرَكَاءُ فِي ثَلاَثٍ فِي الْكَلإِ وَالْمَاءِ وَالنَّارِ
