Mishkat al-Masabih 4374

Abu Umama told that ‘Umar b. al-Khattab put on a new garment and said, “Praise be to God who has clothed me with something with which to cover my nakedness and adorn myself in my lifetime.” He then told that he had heard God's messenger say that if anyone who puts on a new garment says, “Praise be to God who has clothed me with something with which to cover my nakedness and adorn myself in my lifetime,” then takes the old garment and gives it as sadaqa, he will be in God’s protection, guardianship and shelter both when alive and when dead. Ahmad, Tirmidhi and Ibn Majah transmitted it, Tirmidhi saying this is a gharib tradition.
