Munāqib ibn Shahr Āshūb:
It is narrated from a man by the name of ʿAbd al-Raḥmān, who was a teacher for children in Medina. He taught one of the sons of al-Ḥussain عليه السلام, who was named ‘Jaʿfar’. He taught him ‘All praise is due to Allah, the Lord of the Worlds.‘ (al-Ḥamdulillahi Rabb al-ʿĀlamīn) (i.e. al-Fātiḥa).
When his son read it to his father al-Ḥussain عليه السلام, he called for the teacher and gave him one thousand dinars, and one thousand garments, and gave him a plentiful reward (lit. filled his mouth with pearls).
It was said to him: “This [as a compensation] for that?”
He replied: How can what I gave him compare with what he taught my son: ‘All praise is due to Allah, the Lord of the Worlds.’ (al-Ḥamdulillahi Rabb al-ʿĀlamīn) (i.e. al-Fātiḥa). ?
وروي أن رجلا يسمى عبد الرحمن ، كان معلما للأولاد في المدينة ، فعلم ولدا للحسين ( عليه السلام ) يقال له جعفر ، فعلمه * ( الْحَمْدُ لِلَّه رَبِّ الْعالَمِينَ ) * فلما قرأها على أبيه الحسين ( عليه السلام ) استدعى المعلم ، وأعطاه ألف دينار وألف حلة ، وحشا فاه درا ، فقيل له في ذلك ؟ فقال ( عليه السلام ) : وأنى تساوي عطيتي هذه بتعليمه ولدي * ( الْحَمْدُ لِلَّه رَبِّ الْعالَمِينَ ) * ؟
