Musnad Ahmed: Hadith 3278

I stayed overnight in the house of my maternal aunt Maimoonah bint al-Harith. The Messenger of Allah (ﷺ) prayed ‘Isha', then he came back to her, as it was her night. He prayed two rak'ahs, then he turned and said, "Has the boy gone to sleep?" And I could hear him. And I heard him say in his prayer: “O Allah, put in my heart light, in my hearing light, in my seeing light, on my tongue light, give me abundant light.”
