It is from the Sunnah to face the Qiblah in six prayers: the first unit (Rak'ah) of the night prayer (Salat al-Layl), the single unit (Rak'ah) of Witr, the first unit of the two Rak'ahs of noon (Zawal), the first unit of the two Rak'ahs of Ihram, the first unit of the Nawafil (supererogatory) prayers after Maghrib, and the first unit of the obligatory (fardh) prayer, as mentioned by my father (may Allah (swt) be pleased with him) in his message to me.
