Z who whispers into the breasts of mankind,
5 Here it is Satan who whispers into the breasts of mankind, but elsewhere it is the soul that is described as whispering (50:16), prompting to evil (5:30; 20:96), and seducing (12:18). However, the reference here is not to the soul as such, but to the passionate soul, or the soul that commands to evil (al-nafs al-ʿammārah bi-l-suʾ; 12:53), regarding which a famous ḥadīth says, “Truly Satan flows in the blood of the son of Adam” (Q). From one perspective, it is Satan who suggests, tempts, prompts, and whispers, and the passionate soul then follows the caprices that arise rather than the commands of God. From another perspective, only the soul that commands to evil has this propensity. In this vein, 43:36 says, And whosoever turns blindly away from the remembrance of the Compassionate, We assign to him a satan who is then a companion unto him (see also 7:27); regarding the soul that commands to evil, see 12:53c; 75:1-2c; 89:27c.
