4 Quls on a large canvas 

The 4 Quls are known as protecting Surahs. Surah Al-Kafiroun and Al-Ikhlas protect from shirk. Surahs Al-Falaq and An-Naas protect from mischief of created things, envy, magic and the whisperings of the shaitaan. 

According to the Hadith, Surah Al-Ikhlas reward is equivalent to one third of the Quran while Surah Al-Kafiroun is one quarter.
