Imam Malik's Muwatta, Chapter: The Quran

Yahya related to me from Malik from Yahya ibn Said that he had heard that the Messenger of Allah, may Allah bless him and grant him peace, used to say the following dua, "O Allah, it is You who makes the dawn break and makes the night a time for rest and appoints the sun and moon to reckon by. Relieve me of debt and enrich me from poverty and let me enjoy my hearing, my sight and my strength in Your way." Allahumma faliqa'l isbah, wa ja ila'l-layli sakana, wa'sh-shamsi wa'l-qamari husbana. Iqda anniy addayna, wa'ghnaniy mina'l faqr. Na'mti aniy bi samiy wa basariy, wa quwwatiy fi sabilik.
