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