4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ibrahim ibn abu Mahmud who has said the following: “I once asked al-Rida’ , about the two Rak‘at Salat (prayer) after obligatory Tawaf behind Maqam (station) of Ibrahim ‘Alayhi al-Salam where it is today or where it was in the time of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause’. He (the Imam) said, ‘It is where it is today.’”
