I understand. The story is about Musa AS as he prays to Allah for rain with thousands of his people. After the prayer there is still no rain. So Musa AS asks in a dua what he and his people did wrong. Allah, may He be exalted, responds that there is one wrongdoer that had committed sins over 40 years among the thousands and that he/she is the reason why the prayer is not answered. So Musa AS urged all the men and the woman that if they are wrongdoers, they should leave the group. Nobody leaves, and Musa AS prays again. After that, it pours from the sky. So Musa AS asks in a dua to Allah what the reason was of the rainfall, even though no-one left. Allah, may He be exalted, says that the person in dispute made repentance and that He accepted it. I think that the essence of the story is great, and I would like to narrate it further to my friends etc. but therefore I would like to know if it’s fabricated or not.
