Musnad Ahmad 3076

It was narrated that Ibn 'Abbas (رضي الله عنه) said: The Messenger of Allah (ﷺ) was in Maimoonah's house, and I put some water for him to do wudoo’ at night. Maimoonah said to him: O Messenger of Allah, 'Abdullah bin ‘Abbas has put this for you. He said: "O Allah, grant him deep understanding of the faith and teach him the meaning of the Qur’an.”
