Sunan Abi Dawud — Knowledge (Kitab Al-Ilm)

The Prophet (ﷺ) used to relate to us traditions from the children of Isra’il till morning came; he would not get up except for obligatory prayer.

“The Prophet would pray the Friday prayer when the sun was declining.”

“The Messenger of Allah (ﷺ) said to me: ‘Be frequent in saying: “There is no might or power except by Allah, (Lā ḥawla wa lā quwwata illā billāh).” For verily, it is a treasure from the treasures of Paradise.’”

“I was a servant of the Prophet, and Hasan and Husain was brought to him and (the infant) urinated on his chest. They wanted to wash it, but the Messenger of Allah said: ‘Sprinkle water on it, for the urine of a girl should be washed, but the urine of a boy should be sprinkled over with water.'”
