(16) بَاب تَحْرِيشِ الشَّيْطَانِ وَبَعْثِهِ سَرَايَاهُ لِفِتْنَةِ النَّاسِ وَأَنَّ مَعَ كُلِّ إِنْسَانٍ قَرِينًا
Jabir reported that Allah's Apostle (may peace be upqn him) said:
The Satan sends detachments of his own in order to put people to trial and the highest in rank, in his eyes, is one who is most notorious in sowing the seed of dissension.
