Surely...

Surely, Allah, the Exalted, will soon grant you in this very night a son (who will be) a master in this world and the hereafter.” On hearing this, she expressed shyness. When I finished my `Ishā’ prayers, I broke my fast, went to bed and slept. In the depth of the night, I got up for the night prayers. When I finished my night prayers, I saw Narjis fast asleep while there were no signs [of pregnancy] in her.

I sat and performed the rituals/supplications (ta`qībāt) recommended after the prayers and then lied down. Then I got up again fearfully and she was still asleep. Then, she got up, prayed and went to sleep. I went out to check if it was dawn yet [i.e. whether the time of prayers had arrived or not]. At the first break of dawn (al-fajr al-awwal), she was still fast asleep. At this juncture, I became slightly skeptical.

Immediately, [Imam] Abū Muḥammad [al-`Askarī], peace be on him, cried out from where he was, “O Aunt! Don’t be in such a rush! Indeed the affair is near!” I sat down and began reciting the suras of Sajda and Yāsīn. While I was busy [reciting them], she woke up startled. I leapt towards her and said, “I seek Allah’s protection for you! Do you feel anything?” She replied, “Yes, O Aunt!” I said to her, “Be calm and hold your heart.

This is what I had told you.” Then suddenly I felt a weakness in myself and she felt a weakness in herself. I came to with the sound of my master [the Mahdī] and removed the cloth from over him. He was in a state of prostration and was touching the earth with the places [which touch the ground during] prostration. I embraced him and he was absolutely clean and immaculate. (Imam) Abū Muḥammad, peace be on him, called out to me, “O Aunt! Bring my son to me,” and I did.

He placed his hands beneath his lower-back and back and put his feet on his chest. Then, he put his tongue in his mouth and caressed his eyes, ears, and joints. He then said, “Speak, O my son!” He replied, “I testify that there is no god but Allah, He is One and has no partner. I testify that Muḥammad is the Messenger of Allah, Allah's blessings be on him and his family.” He then sent blessings on Amīr al-Mu’minīn and the Imams, peace be on them, until he reached his father.

He then stopped and didn’t continue. (Imam) Abū Muḥammad, peace be on him, called out, “O Aunt! Take him to his mother so that he greets her and then bring him back to me.” I took him to her and he greeted her, then, I took him back [to his father] and put him on the ground.
