Predicting lunar eclipse

Q 3: is it true that the second Ruku`(bowing) of Salat-ul-Kusuf (Prayer at the time of a solar eclipse) is regarded as a Sunnah (a commendable act) so that the latecomer who missed the first Ruku` should make up one full Rak`ah (unit of Prayer) with two Ruku`s (bowings) after the Imam (the one who leads congregational Prayer) makes the Taslim (salutation of peace ending the Prayer) or is it that the second Ruku` replaces the first one? (Part No. 8; Page No. 324)

A: According to the correct view, whoever misses the first Ruku` of Salat-ul-Kusuf is considered to have missed the entire Rak`ah and thus, has to make it up fully with two Ruku`s. This is because Salat-ul-Kusuf is a form of `Ibadah (worship) and `Ibadahs (worships) are Tawqifiy (bound by a religious text and are not amenable to personal opinion) and should only be offered in the manner that is reported in the authentic Hadith.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
