Musnad Ahmad 305
Musnad `Umar b. al-Khattab (ra)
It was narrated that Abul’Ala’ ash-Shami said: Abu Umamah put on a new garment, and when it reached his collarbone he said: Praise be to Allah Who has clothed me with that which conceals my `awrah and with which I may beautify myself in my life. Then he said: I heard `Umar bin al-Khattab (رضي الله عنه) say: The Messenger of Allah (ﷺ) said: `Whoever gets a new garment, and puts it on and says, when it reaches his collarbone, `Praise be to Allah Who has clothed me with that which conceals my ‘awrah and with which I may beautify myself in my life,` then takes the garment that is worn out or that he took off - and gives it in charity, will be in the care of Allah, may He be exalted, and under the protection of Allah in life and in death, in life and in death, in life and in death.`
