Removing harm from the road
مَرَّ رَجُلٌ بِغُصْنِ شَجَرَةٍ عَلَى ظَهْرِ طَرِيقٍ، فَقَالَ: وَاللَّهِ لَأُنَحِّيَنَّ هَذَا عَنِ الْمُسْلِمِينَ لَا يُؤْذِيهِمْ، فَأُدْخِلَ الْجَنَّةَ
Marra rajulun bi-ghusni shajaratin ala dhahri tariq, fa-qal: Wa-llahi la-unahhiyanna hadha ani-l-muslimina la yu'dhihim, fa-udkhila-l-jannah.
"A man passed by a branch of a tree lying across a road. He said: By Allah, I will remove this from the Muslims so it does not harm them. He was admitted to Paradise."
Narrated by Abu Hurayrah. Sahih Muslim 1914
A short reflection
A branch in the road. A picked-up piece of litter. Removing harm from the path of others is named directly as a road to Jannah.
