Ya-Sin is the 36th surah — 83 verses revealed in Mecca, opening with the two disconnected letters Ya, Sin that give it its name. It is among the most frequently recited surahs, and is popularly called "the heart of the Quran," though the report that gives it that title is considered weak by hadith scholars.1
What it is about
The surah presses three points against those who rejected the message. First, that the Prophet ﷺ is "truly one of the messengers, on a straight path," and the Quran a real revelation. Second, that the signs of God are everywhere for those who look — the dead earth revived by rain, the night and day, the sun and moon each in an orbit, the ships that carry people across the sea. Third, and most insistently, that the resurrection is certain. It also tells a parable of a town that drove away the messengers sent to it, and of one man who believed and paid with his life, entering Paradise.
Why it matters
The surah's climax answers the mockery of a man who crumbled an old bone and asked who could give it life. God replies: "Say, 'He will give them life who produced them the first time... Is not He who created the heavens and the earth able to create the likes of them?' ... His command is only when He intends a thing that He says to it, 'Be,' and it is."2 To read Ya-Sin in Arabic with translations and recitation, open it on Quran.com.
