Chapter: The superiority of him who carries the luggage of his companions during a journey

باب فَضْلِ مَنْ حَمَلَ مَتَاعَ صَاحِبِهِ فِي السَّفَرِ
Sahih al-Bukhari 2891

Narrated Abu Huraira:

The Prophet (ﷺ) said, "Charity is obligatory everyday on every joint of a human being. If one helps a person in matters concerning his riding animal by helping him to ride it or by lifting his luggage on to it, all this will be regarded charity. A good word, and every step one takes to offer the compulsory Congregational prayer, is regarded as charity; and guiding somebody on the road is regarded as charity."

حَدَّثَنِي إِسْحَاقُ بْنُ نَصْرٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنْ هَمَّامٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ كُلُّ سُلاَمَى عَلَيْهِ صَدَقَةٌ كُلَّ يَوْمٍ، يُعِينُ الرَّجُلَ فِي دَابَّتِهِ يُحَامِلُهُ عَلَيْهَا أَوْ يَرْفَعُ عَلَيْهَا مَتَاعَهُ صَدَقَةٌ، وَالْكَلِمَةُ الطَّيِّبَةُ، وَكُلُّ خَطْوَةٍ يَمْشِيهَا إِلَى الصَّلاَةِ صَدَقَةٌ، وَدَلُّ الطَّرِيقِ صَدَقَةٌ ‏"‏‏.‏
