The Messenger of Allah ﷺ said, "Every joint of a person owes charity each day the sun rises." He said, "To bring about justice between two people is charity. To help a man onto his mount, lifting him onto it or raising his baggage up for him, is charity." And he said, "A kind word is charity." And he said, "Every step you take toward the prayer is charity, and removing something harmful from the road is charity."
وقال رسول الله ﷺ كل سلامى من الناس عليه صدقة كل يوم تطلع الشمس قال تعدل بين الاثنين صدقة وتعين الرجل على دابته تحمله عليها أو ترفع له متاعه عليها صدقة وقال الكلمة الطيبة صدقة وقال كل خطوة يمشيها إلى الصلاة صدقة وتميط الأذى عن الطريق صدقة
This is a sahih hadith, found in the Sahifah Mufradah, number 70. Muslim narrated it [3:83 S / 1:277 Bulaq] through the route of the Sahifah, and we have given precedence to mentioning Muslim's narration because he narrated it in full, similar to this narration, with a slight difference in some wording. Bukhari narrated it with a similar wording [4:56 T / 6:92-93 Fath] through the route of the Sahifah, but with a difference in the wording, though the meaning is the same. He also narrated it with a similar wording [4:35 T / 6:63 Fath] through the route of the Sahifah, but it does not contain "removing harmful things from the road," and it has an addition, "and guiding along the road is a charity." This is with the dal vowelled with fatha and the lam doubled, meaning explaining it to whoever needs it, and it carries the meaning of guidance, as stated by Hafiz in Fath al-Bari. Bukhari also narrated a portion of it only [3:187 T / 5:226 Fath], also through the route of the Sahifah, and part of it has already been given in abbreviated form at 1:8096, also through the route of the Sahifah, but not through the narration of Abdul-Razzaq. Rather, Imam Ahmad narrated it there from Yahya bin Adam, from Ibn Mubarak, from Mamar, from Hammam bin Munabbih, from Abu Hurairah.As for "sulama," with the sin (undotted) vowelled with damma, the lam unshaddad, and ending in an alif maqsura, it means the joint. It has also been said to mean every hollow bone among the small bones. As for his saying "the sun rises," this is what is established in the original copies of the Musnad and Jami al-Masanid, while in the two narrations of the Sahihayn it reads "the sun rises over it" (fihi), and in the Sahifah Mufradah it reads "the sun rises upon it" (alayhi).
