Hadith: My Cistern takes a month's journey to cross it. Its water is whiter than milk, its smell is nicer than musk,

عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو رضي الله عنهما قَالَ: قالَ النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ:
«حَوْضِي مَسِيرَةُ شَهْرٍ، مَاؤُهُ أَبْيَضُ مِنَ اللَّبَنِ، وَرِيحُهُ أَطْيَبُ مِنَ المِسْكِ، وَكِيزَانُهُ كَنُجُومِ السَّمَاءِ، مَنْ شَرِبَ مِنْهَا فَلاَ يَظْمَأُ أَبَدًا».
[صحيح] - [متفق عليه] - [صحيح البخاري: 6579]

‘Abdullāh ibn ‘Amr (may Allah be pleased with him) reported: The Prophet (may Allah’s peace and blessings be upon him) said:
"My Cistern takes a month's journey to cross it. Its water is whiter than milk, its smell is nicer than musk, and its drinking cups are like the stars of the sky; whoever drinks from it will never become thirsty."
Sahih/Authentic. - [Al-Bukhari and Muslim]

Explanation

The Prophet (may Allah's peace and blessings be upon him) reported that he will have a Cistern on the Day of Judgment whose length takes a month's journey to cross, and so does its breadth; its water is whiter than milk; its smell is more pleasant than the smell of musk; and its drinking cups are as numerous as the stars of the sky. Whoever drinks from that Cistern using these cups will never become thirsty.
