Abu Dhar al-Ghafari said: “The Messenger of Allah (sal Allahu alaihi wasallam) said: ‘Sadaqah is prescribed for every person every day the sun rises.’ I said: ‘O Messenger of Allah, from what do we give sadaqah if we do not possess property ‘He said:’? The doors of sadaqah are takbir (Allahu Akbar), Subhan Allah, Alhamdulillah, La-ilaha-ilAllah, Astaghfirullah, enjoining good, forbidding evil, removing thorns, bones and stones from the paths of people, guiding the blind, listening to the deaf and dumb until you understand them, guiding a person to his object of need if you know where it is, hurrying with the strength of your legs to one in sorrow who is appealing for help, supporting the weak with the strength of your arms. THESE are the DOORS of Sadaqah. “[Ahmad]
In other words one does not only need to have financial resources to earn the reward of Sadaqah. There are many deeds that qualify as Sadaqah with Allah subhana wa ta’ala. In addition to those listed above are the following ordinary courtesies if we do them with the intention of pleasing Allah subhanwata’ala.
1. To administer justice between two people.
2. To assist his mount upon a man so he may ride.
3. To help the one who needs or asks for it; someone with his animal/vehicle, opening doors, give directions, carrying groceries or heavy things for someone.
4. A good word is Sadaqah.
5. Every step taken toward prayer is Sadaqah.
6. Your smile for your brother is Sadaqah.
7. Planting something which a person or animal eats or benefits from.
Abu Musa narrated that the Prophet (s.a.w.s.) said, “Every Muslim has to give in sadaqah (charity).” The people asked, “O Allah’s Messenger (s.a.w.s.)! If someone has nothing to give, what will he do?” He said, “He should work with his hands and benefit himself and also give in charity (from what he earns).” The people further asked, “If he cannot do even that?” He replied, “Then he should help the needy who appeal for help.” Then the people asked, “If he cannot do that?” He replied, “Then he should perform all that is good and keep away from all that is evil and this will be regarded as charitable deeds.” (Bukhari Vol. 2, Hadith 524)
Mu‘aadh bin Jabal (r.a.) related from the Prophet (s.a.w.s.) “Sadaqah extinguishes sin as water extinguishes fire.” (Ahmad, Tirmidhi and Ibn Majah)
