Sahih Bukhari Volume 8, Book 81, Hadith 6570

وَقَالَ ‏{‏غَدْوَةٌ فِي سَبِيلِ اللَّهِ أَوْ رَوْحَةٌ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا، وَلَقَابُ قَوْسِ أَحَدِكُمْ أَوْ مَوْضِعُ قَدَمٍ مِنَ الْجَنَّةِ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا، وَلَوْ أَنَّ امْرَأَةً مِنْ نِسَاءِ أَهْلِ الْجَنَّةِ اطَّلَعَتْ إِلَى الأَرْضِ، لأَضَاءَتْ مَا بَيْنَهُمَا، وَلَمَلأَتْ مَا بَيْنَهُمَا رِيحًا، وَلَنَصِيفُهَا ـ يَعْنِي الْخِمَارَ ـ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا‏)‏‏.‏

The Prophet added, "A forenoon journey or an after noon journey in Allah's Cause is better than the whole world and whatever is in it; and a place equal to an arrow bow of anyone of you, or a place equal to a foot in Paradise is better than the whole world and whatever is in it; and if one of the women of Paradise looked at the earth, she would fill the whole space between them (the earth and the heaven) with light, and would fill whatever is in between them, with perfume, and the veil of her face is better than the whole world and whatever is in it."
