The Prophet ﷺ, Abu Bakr, and Umar used to camp at al-Abtah.
أن النبي ﷺ وأبا بكر، وعمر كانوا ينزلون الأبطح.
Muslim narrated it in Hajj (1310:337) from Muhammad bin Mihran Razi, who said, Abdul-Razzaq narrated to us, from Maamar, from Ayub, from Nafi, from Ibn Umar, and he related it.Bukhari narrated it in Hajj (1768) from Abdullah bin Abdul-Wahhab, who said, Khalid bin Harith narrated to us, he said, Ubaydullah was asked about Muhassab, so Ubaydullah narrated to us, from Nafi, who said, "The Messenger of Allah ﷺ stayed there, and so did Umar and Ibn Umar."And from Nafi, that Ibn Umar used to pray Dhuhr and Asr there, meaning at Muhassab, and I think he also said Maghrib. Khalid said, I have no doubt about Isha. He would also take a nap there, and he would mention this about the Prophet ﷺ.
