Be a stranger or a traveller
كُنْ فِي الدُّنْيَا كَأَنَّكَ غَرِيبٌ أَوْ عَابِرُ سَبِيلٍ
Kun fi-d-dunya ka-annaka gharibun aw abiru sabil.
"Be in this world as if you were a stranger or a traveller on the road."
Narrated by Abdullah ibn Umar. Sahih al-Bukhari 6416 · Nawawi's Forty · #40
A short reflection
Ibn Umar would add: When evening comes, do not wait for morning. When morning comes, do not wait for evening. The traveller does not unpack heavily.
