It refers to Surah Al-Fatiha, the first chapter of the Quran, recited in every unit of Muslim prayers. Known as "The Opening," it is a fundamental part of Islamic worship, seeking guidance, mercy, and blessings from Allah. Surah Al-Fatiha acknowledges Allah's sovereignty, seeks His guidance on the straight path, and expresses reliance on Him. It plays a central role in Islamic rituals and spirituality. It is compulsory for every Muslim to recite this chapter in every rak’ah, during the Qiyam (standing posture) of every prayer.
