I heard Allah's Apostle ﷺ as saying: Verily, the Satan has lost all hopes that the worshippers would ever worship (him) in the peninsula of Arabia, but he (is hopeful) that he would sow the seed of dissension amongst them.

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ إِنَّ الشَّيْطَانَ قَدْ أَيِسَ أَنْ يَعْبُدَهُ الْمُصَلُّونَ فِي جَزِيرَةِ الْعَرَبِ وَلَكِنْ فِي التَّحْرِيشِ بَيْنَهُمْ
