[Machine] Every newborn is born with whisperings in his heart. If he mentions Allah, these whisperings diminish, but if he is negligent, the whisperings increase. This is mentioned in the verse: "The persistent whisperer (devil) who withdraws (upon recitation of the Quran)" [Surah An-Nas: 4].  

مَا مِنْ مَوْلُودٍ إِلَّا عَلَى قَلْبِهِ الْوَسْوَاسُ فَإِنْ ذَكَرَ اللَّهَ خَنَسَ وَإِنْ غَفَلَ وَسْوَسَ وَهُوَ قَوْلُهُ تَعَالَى {الْوَسْوَاسِ الْخَنَّاسِ} [الناس 4]
