Hadith: My Cistern is so large that it takes a month's journey to cross it

عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو 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]

‘Abdullāh ibn ‘Amr (may Allah be pleased with him) reported that the Prophet (may Allah’s peace and blessings be upon him) said: "My Cistern is (so large that it 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) states in the Hadīth that his Cistern is so wide that it takes a month's journey to cross. Another version of the Hadīth mentions that its corners are straight and it is square in shape, indicating its spaciousness and the great distance between its sides and corners. Furthermore, he (may Allah’s peace and blessings be upon him) tells that its water is whiter than milk, its smell is nicer and more pleasant than musk - he mentioned it specifically because it is the best type of perfume - and its drinking cups are as numerous and bright as the stars of the sky. Whoever drinks from this Cistern and its vessels will never go thirsty again.
