Narrated Ruwaifi' bin Thabit (RA):

The Prophet (ﷺ) said: "It is not lawful for a man who believes in Allah and the Last Day to water what another person has sown." [Abu Dawud and at-Tirmidhi reported it. Ibn Hibban graded it Sahih (authentic), and al-Bazzar graded it Hasan (good)].

وَعَنْ رُوَيْفِعِ بْنِ ثَابِتٍ ‏- رضى الله عنه ‏- عَنْ اَلنَّبِيِّ ‏- صلى الله عليه وسلم ‏-قَالَ: { لَا يَحِلُّ لِامْرِئٍ يُؤْمِنُ بِاَللَّهِ وَالْيَوْمِ اَلْآخِرِ أَنْ يَسْقِيَ مَاءَهُ زَرْعَ غَيْرِهِ .‏ } أَخْرَجَهُ أَبُو دَاوُدَ, وَاَلتِّرْمِذِيُّ, وَصَحَّحَهُ اِبْنُ حِبَّانَ, وَحَسَّنَهُ اَلْبَزَّارُ [1]‏ .‏
