813.  Abu Sa`id Al-Khudri (May Allah be pleased with him) reported: When Messenger of Allah (PBUH) wore a new garment, he would name it. For instance, a turban or shirt or cloak and would supplicate: "Allahumma lakal-hamdu, Anta kasautanihi, as`aluka khairahu wa khaira ma suni`a lahu, wa a`udhu bika min sharrihi wa sharri ma suni`a lahu (O Allah, all the praise is for You that You have given it to me to put on. I ask You its goodness and the goodness of the purpose for which it was made, and I seek Your Protection from its evil and the evil of the purpose for which it was made).''
[Abu Dawud and At-Tirmidhi].

Commentary:  This Hadith tells us that we should recite the invocation taught by Messenger of Allah (PBUH) on wearing a new dress. Imam An-Nawawi argues that on wearing a new pair of shoes or something like that one should also recite this prayer.
