Praise Allaah when wearing garment and get your past and future sins forgiven

whoever wears a garment and says:

الحمدُ للهِ الّذي كَساني هذا (الثّوب) وَرَزَقَنيه مِنْ غَـيـْرِ حَولٍ مِنّي وَلا قـوّة .

Al-Hamdu lillaahil-ladhee kasaanee haadha (at-thawb) wa Razaqaneeh min ghayri hawlin minnee wa laa quwwatin

Praise be to Allah who has clothed me with this (garment) and provided it for me without any strength or power on my part

is forgiven his past and future sins.
