Surah Duha (Zuha) is a chapter in the Qur'an, the central religious text of Islam. The word zuha is derived from the Arabic word zuha, meaning "what you have received", "what you have achieved", or "what you have earned".

The purpose of this chapter is to encourage the believers to give to the poor, the needy, and the sick. This is to be done through encouraging them to do good deeds and through praising them for it. Allah promises the rewards of doing good deeds to the poor and needy.

This chapter has a number of rules that must be observed by the believers in order to receive the rewards. These rules are:

The believers must give to the needy and the sick. They must give to the needy and sick people in a way that is easy for them. They must not give to the needy and sick people when they are in a state of mind that prevents them from doing good deeds.
