Final answer:
In Islamic prayers, the first part of Dua typically involves the recitation of Sura Al-Fatiha, the opening chapter of the Qur'an, which is mandatory in every unit of the prayer.
Step-by-step explanation:
The question asks about the Suras that are recited in the first part of Dua in Islamic prayer. Within Islamic tradition, Sura Al-Fatiha or The Opening, is commonly recited during the prayer ritual. Sura Al-Fatiha is considered the most important chapter in the Qur'an and serves as a prayer for guidance, lordship, and mercy. It is an essential part of the Muslim's daily prayers, referred to as Salat, and recitation of this Sura is mandatory in every unit of the prayer.
While Surah Al-Ikhlas, Surah Al-Kafirun, and Surah Al-Mulk also hold significant importance in Islam and are recited in various prayers and at different times, they are not specifically designated for the first part of every prayer like Surah Al-Fatiha.
