صَحِيحُ مُسْلِمٍ
Sahih Muslim 133
The Book of Faith
Clarifying the Waswasah (Whispers, Bad Thoughts) with regard to faith, and what the one who experiences that should say
حَدَّثَنَا يُوسُفُ بْنُ يَعْقُوبَ الصَّفَّارُ، حَدَّثَنِي عَلِيُّ بْنُ عَثَّامٍ، عَنْ سُعَيْرِ بْنِ الْخِمْسِ، عَنْ مُغِيرَةَ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ، قَالَ سُئِلَ النَّبِيُّ صلى الله عليه وسلم عَنِ الْوَسْوَسَةِ قَالَ تِلْكَ مَحْضُ الإِيمَانِ .
It is narrated on the authority of 'Abdullah b. Mas'ud that the Messenger (ﷺ) was asked about evil prompting, to which he replied: It is pure faith.
