Allah's Apostle ( ﷺ) saying like this but with this change of words: "She sometimes finds a way in one flock and then in another flock."  

مسلم:٢٧٨٤bحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ الْقَارِيَّ - عَنْ مُوسَى بْنِ عُقْبَةَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ

عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ غَيْرَ أَنَّهُ قَالَ: ‏ «‏ تَكِرُّ فِي هَذِهِ مَرَّةً وَفِي هَذِهِ مَرَّةً۔»
