اَلْحَمْدُ لِلَّهِ الَّذِي كَسَانِيْ هَذَا الثَّوْبَ وَرَزَقَنِيْهِ مِنْ غَيْرِ حَوْلٍ مِنِّيْ وَلَا قُوَّةٍ

Alhamdu lillaahil-ladhee kasaanee haadhaa aththawba wa razaqaneehi min ghayri hawlim-minnee wa laa quwwah

All Praise is for Allah who has clothed me with this garment and provided it for me, with no power nor might from myself. The Prophet (ﷺ) said, "If anyone says this while wearing clothes, his previous sins will be forgiven."
