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: “Ilbas jadida, wa `ish hamida, wa mut shahida (May you wear new clothes, live a good life and die as martyr).”
