It was narrated that Abu Umamah said:
“Umar bin Khattab put on a new garment and said: Al-hamdu lillahil-ladhi kasani ma uwari bihi ‘awrati, wa atajammalu bihi fi hayati (Praise is to Allah Who has clothed me in something with which I conceal my nakedness and adorn myself in my life). Then he said: ‘I heard the Messenger of Allah ﷺ say: “Whoever puts on a new garment and says: Al-hamdu lillahil- ladhi kasani ma uwari bihi ‘awrati, wa atajammalu bihi fi hayati (Praise be to Allah Who has clothed me in something with which I conceal my nakedness and adorn myself in my life), then takes the garment that has worn out, or that he had taken off and gives it in charity, he will be under the shelter, protection and care of Allah, whether he lives or dies.’ He said this three times.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، قَالَ حَدَّثَنَا أَصْبَغُ بْنُ زَيْدٍ، حَدَّثَنَا أَبُو الْعَلاَءِ، عَنْ أَبِي أُمَامَةَ، قَالَ لَبِسَ عُمَرُ بْنُ الْخَطَّابِ ثَوْبًا جَدِيدًا فَقَالَ الْحَمْدُ لِلَّهِ الَّذِي كَسَانِي مَا أُوَارِي بِهِ عَوْرَتِي وَأَتَجَمَّلُ بِهِ فِي حَيَاتِي ثُمَّ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ " مَنْ لَبِسَ ثَوْبًا جَدِيدًا فَقَالَ الْحَمْدُ لِلَّهِ الَّذِي كَسَانِي مَا أُوَارِي بِهِ عَوْرَتِي وَأَتَجَمَّلُ بِهِ فِي حَيَاتِي . ثُمَّ عَمَدَ إِلَى الثَّوْبِ الَّذِي أَخْلَقَ أَوْ أَلْقَى فَتَصَدَّقَ بِهِ كَانَ فِي كَنَفِ اللَّهِ وَفِي حِفْظِ اللَّهِ وَفِي سِتْرِ اللَّهِ حَيًّا وَمَيِّتًا " . قَالَهَا ثَلاَثًا .
