muslim:1344b – [Chain 1] Zuhayr b. Ḥarb > Ismāʿīl / Ibn ʿUlayyah > Ayyūb [Chain 2] Ibn Abū ʿUmar > Maʿn > Mālik [Chain 3] Ibn Rāfiʿ > Ibn Abū Fudayk > al-Ḍaḥḥāk > Nāfiʿ > Ibn ʿUmar

This hadith has been narrated on the authority of Ibn Umar through another chain of transmitters (but with one alteration) that here Allah-o-Akbar is mentioned twice.  

مسلم:١٣٤٤b – وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ حَدَّثَنَا إِسْمَاعِيلُ يَعْنِي ابْنَ عُلَيَّةَ عَنْ أَيُّوبَ ح وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ حَدَّثَنَا مَعْنٌ عَنْ مَالِكٍ ح وَحَدَّثَنَا ابْنُ رَافِعٍ حَدَّثَنَا ابْنُ أَبِي فُدَيْكٍ أَخْبَرَنَا الضَّحَّاكُ كُلُّهُمْ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ

عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ إِلاَّ حَدِيثَ أَيُّوبَ فَإِنَّ فِيهِ التَّكْبِيرَ مَرَّتَيْنِ
