Al-Mukhtasar
وَمَن يَعْشُ عَن ذِكْرِ ٱلرَّحْمَـٰنِ نُقَيِّضْ لَهُۥ شَيْطَـٰنًا فَهُوَ لَهُۥ قَرِينٌ ﴿٣٦﴾
And whoever turns away from this Qur’ān that was revealed to Muhammad (peace be upon him), I shall set a satan upon him who will lure him with falsehood and lead him astray; it will remain with him wherever he goes.
