وَعَن أبي أُمامةَ قَالَ: لَبِسَ عُمَرُ بْنُ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ ثَوْبًا جَدِيدًا فَقَالَ: الْحَمْدُ لِلَّهِ الَّذِي كَسَانِي مَا أُوَارِي بِهِ عَوْرَتِي وَأَتَجَمَّلُ بِهِ فِي حَيَاتِي ثُمَّ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: " مَنْ لَبِسَ ثَوْبًا جَدِيدًا فَقَالَ: الْحَمْدُ لِلَّهِ الَّذِي كَسَانِي مَا أُوَارِي بِهِ عَوْرَتِي وَأَتَجَمَّلُ بِهِ فِي حَيَاتِي ثُمَّ عَمَدَ إِلَى الثَّوْبِ الَّذِي أَخْلَقَ فَتَصَدَّقَ بِهِ كَانَ فِي كَنَفِ اللَّهِ وَفِي حِفْظِ اللَّهِ وَفِي سِتْرِ اللَّهِ حَيًّا وَمَيِّتًا ". رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَابْنُ مَاجَهْ وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيثٌ غَرِيبٌ
English Translation
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.
