[Machine] When the emigrants arrived in the city, they disliked the water. There was a man from the Banu Ghifar tribe who had a spring called Ruma. He used to sell water from it in exchange for a measure of dates. The Messenger of Allah ﷺ said to him, "Sell it to me for an eye in Paradise." He said, "O Messenger of Allah, I and my family have nothing else besides it. I cannot give it up." Uthman then heard about it and he bought it from him for thirty-five thousand dirhams. Then he came to the Prophet ﷺ and said, "O Messenger of Allah, will you make for me what you made for him an eye in Paradise if I buy it?" He said, "Yes." He said, "I have bought it and made it for the Muslims."

لَمَّا قَدِمَ الْمُهَاجِرُونَ الْمَدِينَةَ اسْتَنْكَرُوا الْمَاءَ وَكَانَتْ لِرَجُلٍ مِنْ بَنِي غِفَارٍ عَيْنٌ يُقَالُ لَهَا رُومَةٌ وَكَانَ يَبِيعُ مِنْهَا الْقِرْبَةَ بِمُدٍّ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ «بِعْنِيها بِعَيْنٍ فِي الْجَنَّةِ» فَقَالَ يَا رَسُولَ اللهِ لَيْسَ لِي وَلَا لِعِيَالي غَيْرُهَا لَا أَسْتَطِيعُ ذَلِكَ فَبَلَغَ ذَلِكَ عُثْمَانَ ؓ فَاشْتَرَاهَا بِخَمْسَةٍ وَثَلَاثِينَ أَلْفَ دِرْهَمٍ ثُمَّ أَتَى النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللهِ أَتَجْعَلُ لِي مِثْلَ الَّذِي جَعَلْتَهُ له عَيْنًا فِي الْجَنَّةِ إِنِ اشْتَرَيْتُهَا؟ قَالَ «نَعَمْ» قَالَ قَدِ اشْتَرَيْتُهَا وَجَعَلْتُهَا لِلْمُسْلِمِينَ
