(continued) Abbas ibn Abdul Muttalib narrates that he saw Sayyedah Fatemah binte Asad ibn Hashim (peace be upon her), the respected mother of Ameerul Momineen (peace be upon him) come to the Holy Kaabah while she was nine months pregnant and ask Allah the Most High through the right of her son Ameerul Momineen (peace be upon him) to make the birth of Ameerul Momineen (peace be upon him) easy for her.
When Sayyedah Fatimah binte Asad spoke with these words of Dua, we saw that the House of Allah split from its back and Sayyedah Fatimah entered through that opening and vanished from our sight and then the opening closed and joined together with the permission of Allah. Then we intended to open the door (of the Holy Kaabah) to send some of our ladies to her (peace be upon her) but the door did not open.
Then we realized that this is a matter from the matters of Allah.
Sayyedah Fatimah (binte Asad) (peace be upon her) remained in the House (of Allah) for three days.
He narrated: The people of Mecca discussed this continuously and the women discussed this inside their closed houses.
