Question: why is surah ikhlas called ikhlas?
Answer: A sahabi, as the word is commonly used today, is someone who saw Prophet Muhammad, believed in him and died as a Muslim. Surah 112 Al-Ikhlas (also known as The Purity, The Sincerity or the Surah of Tawheed) is only four aayaat (verses) yet it sums up the essence of Islam.
