Seeking refuge in Muhammad

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ - وَاللَّفْظُ لاِبْنِ الْمُثَنَّى - قَالاَ حَدَّثَنَا ابْنُ، أَبِي عَدِيٍّ عَنْ شُعْبَةَ، عَنْ سُلَيْمَانَ، عَنْ إِبْرَاهِيمَ التَّيْمِيِّ، عَنْ أَبِيهِ، عَنْ أَبِي مَسْعُودٍ، أَنَّهُ كَانَ يَضْرِبُ غُلاَمَهُ فَجَعَلَ يَقُولُ أَعُوذُ بِاللَّهِ - قَالَ - فَجَعَلَ يَضْرِبُهُ فَقَالَ أَعُوذُ بِرَسُولِ اللَّهِ ‏.‏ فَتَرَكَهُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ وَاللَّهِ لَلَّهُ أَقْدَرُ عَلَيْكَ مِنْكَ عَلَيْهِ ‏"‏ ‏.‏ قَالَ فَأَعْتَقَهُ ‏.‏

Abu Mas'ud reported that he had been beating his slave, and he had been saying: I seek refuge in Allah, but he continued beating him, whereupon he said: I seek refuge in Allah's Messenger, and he spared him. Thereupon Allah's Messenger (ﷺ) said: By Allah, God has more dominance over you than you have over him (the slave). He said that he set him free.
