At the time of Bani Israel, there was a man in a small village, called Barsisa. He was, what you call, a monk. But he was a true Christian. He believed in Tawheed and believed Isa (peace be upon him) was a messenger of Allah.
One day three brothers decided to go for Jihad. But they had a sister and they did not want to leave her alone. So they went looking for someone to take care of her. The town people suggested to leave her with Barsisa, because of his piety.
So they went to him and when they asked him, he said, “I seek refuge from the cursed Shaytan” and said No! This was because he was scared of falling into sin ( due to the potential fitnah it may cause).
Then Shaytan came to Barsisa in the form of Waswasah (Whisperings). Shaytan is very smart and knew Barsisa had a soft heart. So he told Barsisa, “What if they can’t find someone good and leave her with someone bad, wouldn’t that be your fault?”
Now Barsisa did not realise this was Shaytan whispering in his heart, and because of his compassion for others, he decided to accept their request and help the woman.
He let her stay in a house opposite the church. He did this so that it would be easy for him to leave her her food outside the church and she could come get it herself. But after sometime, shaytan returned. This time he told Barsisa, “Why don’t you leave the food closer for her, so that people don’t see her moving back and forth alone!” Barsisa agreed and started leaving the food outside the house. But shaytan wasn’t happy with this either, so sometime later, he returned and ask Barsisa, “Why don’t you go in and leave it on the table, so that no one sees her coming out and going in alone all the time!” Again, Barsisa agreed and he started leaving the food on the table.
