عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَيْسَ مِنْكُمْ مِنْ أَحَدٍ إِلَّا وَقَدْ وُكِّلَ بِهِ قَرِينُهُ مِنَ الشَّيْطَانِ قَالُوا وَأَنْتَ يَا رَسُولَ اللَّهِ قَالَ نَعَمْ وَلَكِنَّ اللَّهَ أَعَانَنِي عَلَيْهِ فَأَسْلَمَ
It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: With every one of you, a companion from among the devils has been appointed. The people asked: O Messenger of Allah! Is there one with you as well? He (peace and blessings be upon him) said: Yes, but Allah Almighty has helped me against him and he has become obedient.
