(45) باب اسْتِحْبَابِ إِدَامَةِ الْحَاجِّ التَّلْبِيَةَ حَتَّى يَشْرَعَ فِي رَمْىِ جَمْرَةِ الْعَقَبَةِ يَوْمَ النَّحْرِ
'Abd al-Rahman b. 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: Hive the people forgotten (this Sunnah of the Holy Prophet) or have they gone astray? I heard him, upon whom Sibrah al-Baqara was revealed, pronouncing Talbiya at the very place.
