Imam Reza’s sister, Hakima, narrates that one day Imam (A S.) requested her to stay in his house since a child was to be born from Khizran.
The news that a child was to be born from Khizran surprised Hakima since no one had told her before that Khizran was expecting a child, and more surprisingly, she showed no signs of pregnancy!
However, in obedience to her brother’s request, she stayed behind and even called two other women in the neighbourhood to be around to help her take care of Khizian when she was ready to deliver a child.
After mid-night, Khizran started showing signs of pregnancy and went into labour-pains. At dawn (‘Subh Sadiq) a baby-boy was born. Me went into prostration (‘.Sajda’) in prayers to Allah.
Imam Reza (AS.) then entered the scene. Hakima wrapped die child in a white cloth, and handed him to the imam (A S.), who read ‘Azan’ in the child’s right ear and ‘Ikamah’ in his left ear.
The Imam (A.S ) then returned the child to his sister Hakima, instructing her to keep him with her for three days. On the third day, the child opened his eyes, looked at the sky and read the “Qalema”. Hakima was overjoyed.
She reported what she had seen and heard to her brother, Imam Reza (A.S.) who then informed her that this unusual behaviour of the child should not surprise her since this was not an ordinary child but Allah’s representative on the earth.
Then Imam Reza (AS) named the child Muhammad. “Manaqib”, relates that he saw the seal of Imamat on the place between the shoulders of Imam Taqi (A.S.)
