عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ أَخَذَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِبَعْضِ جَسَدِي فَقَالَ ((اعْبُدِ اللَّهَ كَأَنَّكَ تَرَاهُ وَكُنْ فِي الدُّنْيَا كَأَنَّكَ غَرِيبٌ أَوْ عَابِرُ سَبِيلٍ))
Hazrat Abdullah bin Umar (may Allah be pleased with them both) says: The Messenger of Allah (peace and blessings be upon him and his family) took hold of a part of my body and said: Worship Allah as if you are seeing Him, and be in this world as if you are a stranger or a traveler.
