Mishkat al-Masabih #1475

Abud Darda’ said he heard God’s messenger say, "If one of you has any complaint, or if a brother of his complains of it, he should say, ‘Our Lord God who art in heaven, hallowed be Thy name. Thy command is in the heaven and the earth. As Thy mercy is in the heaven so place Thy mercy in the earth. Forgive us our faults and sins. Thou art the Lord of the good ones. Send down some of Thy mercy and some of Thy healing on this pain’ and it will be cured.” Abu Dawud transmitted it.
