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 ".
