Final answer:
The fourth part of a Dua does not have a universally specified Surah to be recited and could vary by tradition. Surah Al-Falaq and Surah Al-Mulk are commonly recited for particular blessings and protection, whereas Surah Al-Baqarah and Surah Al-Anfal are less likely to be choices due to their length and content.
Step-by-step explanation:
The fourth part of a Dua refers to a custom in Muslim prayers where specific Surahs (chapters) from the Qur'an are recited. The Surahs recited can vary depending on the practice and the occasion. The options provided are: a) Surah Al-Mulk, b) Surah Al-Baqarah, c) Surah Al-Falaq, and d) Surah Al-Anfal.
It is important to note that there are no strict prescriptions in Islamic practice that specify reciting a particular Surah in the 'fourth part' of a Dua. However, among the given options, Surah Al-Falaq and Surah Al-Mulk are often recited for protection and blessings. Surah Al-Baqarah is the longest Surah and is unlikely to be recited in its entirety during a Dua. Surah Al-Anfal contains verses related to various topics including the spoils of war. Therefore, without a specific tradition or context, it's not possible to definitively answer which Surah is recited in the fourth part of a Dua.
To answer the question, one would need to know the specific traditions or context in which the Dua is being performed.
