Reciting some Ayahs of the Qur'an after Surah Al-Fatihah

Q 3: Is it Wajib (obligatory) that a person recites a Surah (Qur'anic chapter) or some Ayahs (Qur'anic verses) after reciting Surah Al-Fatihah in a Sunnah (supererogatory) Prayer?

A: The Prophet (peace be upon him) used to recite Surah Al-Fatihah along with one or more other Surahs (Qur’anic chapters) in each Rak‘ah (unit of Prayer). However, if a Muslim prays a Nafilah (supererogatory prayer) and recites only Surah Al-Fatihah in each Rak‘ah, this will be sufficient. However, it is better and preferable that a Muslim recites Surah Al-Fatihah along with another Surah or part of it, so as to follow the example of the Prophet (peace be upon him).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
