Muhammad ibn Hasan reported that Imam Al-Askari (a.) said:“The believer has five characteristics: Praying the fifty-one bows, visiting on the fortieth day of death, wearing the ring on the right hand, placing the forehead on earth, and reciting aloud: “In the name of God, the Gracious, the Merciful.” [Iqbal-ul-A’mal by Ibn Tawus, page 66.]
