Answer
I say, and with God's help: The Murji'ah are multiple sects mentioned by Al-Laknawi in his valuable book (Al-Raf' wal-Takmil), among them are the Murji'ah of Ahl al-Sunnah, which states that the one who commits a major sin is in God's hands; if He wills, He punishes him, and if He wills, He shows him mercy. There are also the disbelieving Murji'ah, who say that no sin harms one who says (There is no god but Allah). And God knows best.
