Combining the intention of offering a Sunnah Ratibah and Tahiyyat-ul-Masjid

Q 5: Can tahiyyat-ul-Masjid (two-unit-Prayer to greet the mosque) and Sunnah Ratibah (supererogatory Prayer performed on a regular basis) be combined and performed as one Salah with one intention or should Tahiyyat-ul-Masjid be performed first and then the Sunnah Ratibah? A: One of the rules of Fiqh (Islamic jurisprudence) states that: if two acts of ‘Ibadah (worship) of the same type coincide, their acts are merged and one performance shall suffice for both, if the purpose is one. This rule applies to the case of one who enters the Masjid at the time of Sunnah Ratibah for example, so they offer a two-Rak‘ah prayer intending with performing it both: Sunnah Ratibah and Tahiyyat-ul-Masjid, they will earn the virtue of both. The same will be the case for one who swears multiple oaths (Part No. 6; Page No. 141

The same will be the case for one who swears multiple oaths (Part No. 6; Page No. 141) related to one thing, but breaks the oath several times before making Kaffarah (expiation); one Kaffarah will be sufficient for all the broken oaths.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
