It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) used to supplicate with these words: "'Allahumma inni a'udhu bika min ghalabat al-dayn, wa ghalabat al-'aduww, wa shamatat al-a'da'' (O Allah, I seek refuge in You from being overcome by debt, from being overcome by the enemy, and from the gloating of enemies)."
