'Abdul Rahman bin Yazid reported that 'Abdullah (b. Mas'ud) pronounced Talbiya as he returned from the gathering of the people (at Muzdalifa). It was said: He might be a Bedouin (not knowing correctly the rituals of Hajj and, therefore, pronouncing Talbia at this stage), whereupon'Abdullah said: Have the people forgotten (this Sunnah of the Holy Prophet) or have they gone astray? I heard him, upon whom Surah al-Baqarah was revealed, pronouncing Talbiya at the very place.
