(It should be noted that the night of Thursday is Wednesday night as we know it in the west).
According to another traditional report, this one transmitted on the authority of Abu Salih, Abu Huraira (may Allah be well pleased with him) stated that 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 night, at some point between the [obligatory prayers of] sunset [al-maghrib] and late evening [al-'isha']--reciting in each cycle the Opening Sura of the Book [Fatihat al-Kitab] one time, "Qul Huwa'llahu Ahad [Say: 'He is Allah, One!']" five times, and the Two Pleas for Divine Refuge [al-Mu'awwidhatain] five times--and if, when he has finished performing his ritual prayer [salat], he begs forgiveness of Allah (Exalted is He) fifteen times, and donates the spiritual reward for it [his prayer] to his parents--he will have discharged his obligation to them both, even if he has been undutiful ['aqq] in his treatment of them, and Allah (Glorified and Exalted is He) will grant him the gracious favor that He bestows upon the champions of truth [siddiqin] and the martyrs [shuhada'].
