The Messenger of Allah [SAW] used to say these words in his supplication: "Allahumma inni a'udhu bika min ghalabatid-dain, wa ghalabatil-'aduwwi, wa shamatatil-a'da'. (O Allah, I seek refuge with You from being overwhelmed with debt, from being overpowered by the enemy and from the enemy rejoicing over my misfortunes.)'"  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَدْعُو بِهَؤُلاَءِ الْكَلِمَاتِ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ غَلَبَةِ الدَّيْنِ وَغَلَبَةِ الْعَدُوِّ وَشَمَاتَةِ الأَعْدَاءِ
