The title of Surah Ar-Rahman (سورة الرحمن) comes from the first verse, "Ar-Rahman" (The Most Merciful), which is one of the names of Allah. It emphasizes Allah's mercy and countless blessings upon humanity and creation.
This surah (Chapter 55 of the Quran) is often called "The Surah of Mercy" because it repeatedly highlights Allah’s generosity, particularly through the refrain:
"فَبِأَيِّ آلَاءِ رَبِّكُمَا تُكَذِّبَانِ"
"So which of the favors of your Lord will you deny?"
