Statement about Satan moving within the human body
Hadith 926
وَبِهَذَا، عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: ((إِنَّ الشَّيْطَانَ يَتَنَقَّلُ فِي جِسْمِ ابْنِ آدَمَ فَإِذَا عَصَمَهُ اللَّهُ مِنْ بَابٍ تَحَوَّلَ لَهُ مِنْ بَابٍ آخَرَ حَتَّى يُهْلِكَهُ لِغَضَبِهِ)).
With this (previous) chain of narration, the Messenger of Allah, peace and blessings be upon him, said: "Satan moves within the human body, so when Allah saves him from one door, he comes from another door until he destroys some part of him."
