1. Ali ibn Ibrahim has narrated from his father from al-Hassan ibn Mahbub from ibn Sinan who has said the following:

“I once asked abu ‘Abd Allah , about the words of Allah, the Most Majestic, the Most Glorious, ‘The first ever house built for people is that which is in Bakkah, the blessed and a guide for the worlds. In it there are signs which are very clear.’ (3:96-97) I asked, ‘What are these signs which are very clear?’ He (the Imam) said, ‘One of them is the site where Ibrahim stood on the rock. His foot left a clear mark of it. Another sign is the Black Stone, and yet one more sign is the house of Isma‘il.’”
