From the page 193, the death of the father of Sayyida Abu Sa'id Khudri, on the chapter about "The Story of the Companions of the Prophet."
Sayyida Abu Sa'id Khudri said, "I was shown to join the battle of Uhud. At that time, I was thirteen years old. The Prophet did not accept me. My father also tried to support me by saying," His energy is strong, his bones are large. . "Rasulullah SAW looked me up and down. Finally because I was too young, he still did not allow me. My father joined the war and he was martyred. We did not have any property. I went to see the Prophet SAW with intention to ask for something. Seeing me, the Prophet SAW continued to say, "Whoever asks for patience, Allah Almighty will grant him purity of heart and whoever desires wealth of heart, Allah will grant him purity of heart and whoever desires wealth of heart, Allah will grant him wealth of heart. " Listening to those words, I didn't ask for anything at all. Instead I secretly went home."
