باب بَيَانِ أَنَّ اسْمَ الصَّدَقَةِ يَقَعُ عَلَى كُلِّ نَوْعٍ مِنَ الْمَعْرُوفِ ‏‏

Hammam b. Munabbih reported that-this is out of (those ahadith) which Abu Huraira narrated to us from Muhammad, the Messenger of Allah (ﷺ). And he while making a mention of ahadith reported from Allah's Messenger (ﷺ) said this:

Sadaqa is due on every joint of a person, every day the sun rises. Administering of justice between two men is also a Sadaqa. And assisting a man to ride upon his beast, or helping him load his luggage upon it, is a Sadaqa; and a good word is a Sadaqa; and every step that you take towards prayer is a Sadaqa, and removing of harmful things from the pathway is a Sadaqa.
وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ بْنُ هَمَّامٍ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ، مُنَبِّهٍ قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ مُحَمَّدٍ، رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ كُلُّ سُلاَمَى مِنَ النَّاسِ عَلَيْهِ صَدَقَةٌ كُلَّ يَوْمٍ تَطْلُعُ فِيهِ الشَّمْسُ - قَالَ - تَعْدِلُ بَيْنَ الاِثْنَيْنِ صَدَقَةٌ وَتُعِينُ الرَّجُلَ فِي دَابَّتِهِ فَتَحْمِلُهُ عَلَيْهَا أَوْ تَرْفَعُ لَهُ عَلَيْهَا مَتَاعَهُ صَدَقَةٌ - قَالَ - وَالْكَلِمَةُ الطَّيِّبَةُ صَدَقَةٌ وَكُلُّ خَطْوَةٍ تَمْشِيهَا إِلَى الصَّلاَةِ صَدَقَةٌ وَتُمِيطُ الأَذَى عَنِ الطَّرِيقِ صَدَقَةٌ ‏"‏ ‏.‏
