It is located in Wadi Tuwa in Makkah. Al-Shafiʿi says the valley was named Dhu Tuwa because of a well that was there, covered with stones. It is said that the well was dug by ʿAbd Shams bin ʿAbd Manaf bin Qusayy. His daughter, Subayʿa bint ʿAbd Shams, boasted proudly of this well in one of her poems. The Prophet stayed at the well of Tuwa in the valley of Tuwa on the night of his arrival for the Compensatory Umrah [ʿUmrat al-Qaḍāʾ] and the Farewell Pilgrimage. On the day of the Conquest of Makkah, he stopped here to divide his army and gave them orders to enter Makkah. A hadith of ʿAbd Allāh bin ʿUmar bin al-Khattab states: “It is said that, when he arrived in Makkah, the Prophet (PBUH) used to spend the night in Dhu Tuwa until he prayed the Fajr prayer. The place where the Prophet prayed was on a rough mound, not in the mosque that was built there later, but lower down on a rough, coarse mound.”
