There was however a well named Rūmah, and the owner of this would sell water from this well. The Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم then guaranteed a spring in Paradise for whoever bought this well and gave to the Muslims to use freely. When news of this reached Sayyiduna ꜤUthmān رَضِىَ اللهُ عَـنْهُ, he purchased the well and gave it as endowment in the way of Allah Almighty. ^[1]

The renowned hadith expert, Shaykh ꜤAbd al-Haqq al-Dīhlawī رَحْمَةُ الـلّٰـهِ عَـلَيْه writes:

This well was owned by a non-Muslim. ꜤUthmān b. ꜤAffān رَضِىَ اللّٰهُ عَـنْهُ purchased half of it from him for 12,000 dirhams. Now, because half of the well had become an endowment, nobody needed to buy its water. That non-Muslim then struggled to earn anything from it. As a result, he also sold the other half for 8,000 dirhams.^[2]

This means Sayyiduna ꜤUthmān رَضِىَ اللهُ عَـنْهُ purchased this well for 20,000 dirhams in total. After commissioning it for free use by the Muslims, he attained glad tidings of Paradise in return.

O Allah! Make Paradise necessary for ꜤUthmān!

Dear Islamic brothers! This well bears unique distinction, as its water was drank by none other than the Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم.

One day, the Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم passed by this well. It was said to him, that this was the well Sayyiduna ꜤUthmān رَضِىَ اللهُ عَـنْهُ bought and gave away in charity. Hearing this, the Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم made dua by saying, “O Allah! Make Paradise necessary for him!”
