After that, Barsisa the Abid used to leave food at his doorstep and the young woman had to come out of her house and walk all the way to take the food from his doorstep. Barsisa never used to leave from his monastery. Barsisa had never met her and they were not seeing each other. Days passed by like this.
One day, Shaytan came to Barsisa and said, "Somebody might see her when she is walking out. So rather than have her leave from her house. You need to carry it and leave at her doorstep." So he started leaving the food at her doorstep. This happened for many days.
Again one day, Shaytan came to Barsisa and said, "You can't just leave the food at her doorstep. Somebody might see her when she opens the door and she is very beautiful. You would have to take the food and leave it inside her room." So Barsisa would go and knock on the door. She would open and he would walk inside and leave the food there. That continued for a while.
Then again one day Shaytan said, "You can't leave this poor woman alone without giving her any company. Nobody is speaking to her. So she may be feeling very lonely and that might lead to haram. So why don't you go and talk to her from behind the door." Barsisa liked the idea and so for a while he would sit outside and just talk to her for HOURS. Slowly and slowly the relationship was building up and Shaytan was finding it easier to drag him to the next step.
Shaytan then came and said, "You can't just sit there talking to her, people might see you. You need to go inside, just sit in another room without looking at her and talk to her." So for sometime that is what he did. Slowly she started getting closer to him and everytime they got more and more close to the extent that eventually he comitted zina (fornication) with her.
So the Abid, the worshipper who devoted his life to service in the monastery comitted zina. Because of that, she became pregnant and delivered a boy.
