Ibn Umar (may Allah be pleased with them both) said: The Prophet (peace and blessings be upon him), Abu Bakr and Umar (may Allah be pleased with them both) used to stay at al-Abtah. Sakhr bin Juwayriyah narrates from Nafi' that Ibn Umar (may Allah be pleased with them both) considered stopping at al-Muhassab a Sunnah, and he would pray the Zuhr prayer at al-Muhassab on the day of departure. Nafi' said: The Messenger of Allah (peace and blessings be upon him) and the Caliphs after him halted at al-Muhassab.
