Imam al-Bukhārī reported with his chain of transmission to Abū ‘Abd al-Raḥmān al-Sulamī: ‘Uthmān, may Allah be pleased with him, said: "I adjure you by Allah, and I adjure only the companions of the Prophet ﷺ, do you not know that the Messenger of God ﷺ said: 'Whoever digs Rūma will be rewarded with Paradise,' and so I dug it. Do you not know then that he said: 'Whoever equips the army of al-‘Usra will be rewarded with Paradise,' and so I equipped it." He then said that they believed the words of ‘Uthmān.
And in another version from al-Bukhārī: ‘Uthmān, may Allah be pleased with him, reported that the Prophet ﷺ said: "Who would buy the well of Rūma while leaving his share equal to those of all the other Muslims?" So ‘Uthmān bought it.
The well of Rūma is located in the district of al-‘Aqīq al-Aṣghar, on the northwest side of the al-Qiblatayn Mosque. The water of this well is abundant, sweet, clear, and very light. Today, the well and its farms are an integral part of the endowments of the Mosque of Madinah. This endowment has an official document registered with the Saudi administration, accompanied by a vast plot of land covering an area of 108,449.43 square meters. Furthermore, this endowment, better known today as the Well of ‘Uthmān, is authentically linked to ‘Uthmān ibn ‘Affān. This was attested by him and witnessed by a large number of companions. This testimony is confirmed by authentic hadiths. It is one of the most important endowment legacies preserved across the Islamic centuries, from the time of the Prophet ﷺ to the present day. It is one of the signs of God, a well hundreds of years old, in a land where drought is widespread, where rain is scarce, and where there are neither rivers nor lakes. Consequently, this endowment is a legal deed preserved by the Department of Awqāf of Madinah. The two attached aerial photos show the vastness of the farm as well as its large adjoining lands and the development of urbanization.
