Yā Sīn [2] (also Yaseen; Arabic: يٰسٓ, yāsīn; the letters ' Yāʼ ' and ' Sīn ') is the 36th chapter of the Quran. It has 83 verses ( āyāt ). It is regarded an earlier "Meccan surah". Some scholars maintain that verse 12 is from the Medinan period. [3] While the surah begins in Juz' 22, most of it is in Juz' 23. YaTmG1K.
