According to a traditional report transmitted by 'Ikrima, on the authority of Ibn 'Abbas (may Allah be well pleased with him and with his father), Allah's Messenger (Allah bless him and give him peace) once said:
If someone performs two [voluntary] cycles of ritual prayer [rak'atain] on a Thursday, at some point between the [obligatory prayers of] noon [az-zuhr] and afternoon [al-'asr]-reciting in the first cycle the Opening Sura of the Book [Fatihat al-Kitab] one time, and the Verse of the Throne [Ayat al-Kursi] one hundred times, and in the second cycle the Opening Sura of the Book [Fatihat al-Kitab] [one time], and "Qul Huwa'llahu Ahad [Say: 'He is Allah, One!']" one hundred times-and if, when he has finished [performing the ritual prayer], he invokes Allah's blessing upon me one hundred times-Allah (Exalted is He) will grant him the spiritual reward of someone who fasts in the months of Rajab, Sha'ban and Ramadan. The amount of his spiritual reward will be comparable to that of a Pilgrim of the House [of Allah] [Hajj al-Bait]. As for the good deeds to be recorded in his credit column, their number will be equal to the total figure arrived at by adding up all the people who believe in Allah (Exalted is He) and put their trust in Him.
