Sahih Muslim Book 7, Hadith Number 3011.

Chapter : Excellence of making a halt at al Muha’ab, on the day of Nahr, and observing prayer there.

Ibn ‘Abbas (Allah be pleased with them) reported: Halt at Muhassab is not something (significant from the point of view of the Shari’ah). It is a place of halt where Allah’s Messenger (way peace be upon him) halted.
