The Messenger of Allah [SAW] used to say supplication in these words: "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 by debt and from being overpowered by the enemy, and from the enemy rejoicing at my misfortune.)"  

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