It was narrated from Ibn `Umar that the Messenger of Allah (ﷺ) 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:
الْبَسْ جَدِيدًا وَعِشْ حَمِيدًا وَمُتْ شَهِيدًا
TRANSLATION:
May you wear new clothes, live a good life and die as martyr.
