The Duha Prayer

556. Abu Hurayra, may Allah be pleased with him, said, “My friend, peace and blessings be upon him, ordered me to do three things: to fast three days every month, to do the two units of the Duha Prayer and to do the witr before sleeping.” (Sahih al-Bukhari, Sawm, 60; Sahih Muslim, Salatu’l-Musafirin, 85).
Annotation: Performing the Witr Prayer before going to sleep is to be practiced by those who cannot make sure whether they can get up for Tahajjud Prayer. Normally, it is more meritorious to get up in the night and offer the Witr after Tahajjud.

557. Abu Dharr, may Allah be pleased with him, reported that the Prophet, peace and blessings be upon him, said, “When you get up in the morning, charity is due from every one of your joints. There is charity in every ascription of glory to Allah (Subhanallah); there is charity in every utterance of praise of Him (Alhamdulillah); there is charity in every declaration that He is the only true Allah (La ilaha illa’llah); there is charity in every declaration of His Greatness (Allahu Akbar); there is charity in enjoining good; there is charity in forbidding evil. Two units of Duha (Forenoon Prayer) is equal to all this (in reward).” (Sahih Muslim, Salatu’l-Musafirin, 84, Zakah, 56).
