from the Prophet ﷺ, that he said to Mu'awiyah: "O Allah, make him a guiding one, and guide (others) by him."  

عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَمِيرَةَ وَكَانَ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ لِمُعَاوِيَةَ اللَّهُمَّ اجْعَلْهُ هَادِيًا مَهْدِيًّا وَاهْدِ بِهِ  

"When 'Umar bin Al-Khattab removed 'Umair bin Sa'd as governor of Hims, he appointed Mu'awiyah. The people said: 'He has removed 'Umair and appointed Mu'awiyah.' So 'Umair said: 'Do not mention Mu'awiyah except with good, for indeed, I heard the Messenger of Allah ﷺ saying: "O Allah guide (others) by him."  

النَّاسُ عَزَلَ عُمَيْرًا وَوَلَّى مُعَاوِيَةَ فَقَالَ عُمَيْرٌ لاَ تَذْكُرُوا مُعَاوِيَةَ إِلاَّ بِخَيْرٍ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ اللَّهُمَّ اهْدِ بِهِ
