Sunan Ibn Majah, Hadith 3558 ⓘ
It was narrated from Ibn `Umar that the Messenger of Allah saw `Umar wearing a white shirt and he said: “Is this garment of yours washed or a new one?” He said: “Rather it has been washed.” He said: “Ilbas jadida, wa `ish hamida, wa mut shahida (May you wear new clothes, live a good life and die as martyr).”
حَدَّثَنَا الْحُسَيْنُ بْنُ مَهْدِيٍّ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَنْبَأَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ رَأَى عَلَى عُمَرَ قَمِيصًا أَبْيَضَ فَقَالَ " ثَوْبُكَ هَذَا غَسِيلٌ أَمْ جَدِيدٌ " . قَالَ لاَ بَلْ غَسِيلٌ . قَالَ " الْبَسْ جَدِيدًا وَعِشْ حَمِيدًا وَمُتْ شَهِيدًا " .
