In the name of Allah
After passing away of Holy Muhammad, Salman Farsi was severely affected so, he could not meet Fatima and Ali for 10 days.
During this time (Ninth day), a gift from Paradise had come to Fatima. She decided to give the Salman a date from this heavenly gift.
On the tenth day Salman left the house and saw Ali. Ali told him that you persecuted us.
Salman told Ali that, for these 10 days, sadness did not let me to meet you, I never did not want to persecute you.
Ali told him, meet Fatima. she wants to give you a gift from Paradise. Salman wondered that a gift from Paradise came after the prophet.
He went to Fatima and Fatima gave him the date. The eleventh day Salman met Fatima again. In this meeting Fatima taught him a Divine text for fever. This prayer is known as the light/NOOR.
I've brought this text here in Arabic, but the several issues draw attention before reading prayer.
In this situation, why Fatima taught pray for fever?
What wrongdoing Salman made to the Prophet's family with his absence?
… And one of the most important questions is; Why NOOR?
