جماع أبواب الأذان والإقامةChapters on Adhan and Iqamah
(200) بَابُ إِيجَابِ إِعَادَةِ الصَّلَاةِ الَّتِي لَا يُتِمُّ الْمُصَلِّي فِيهَا سُجُودَهُ،Chapter 200: Obligation to repeat the prayer if prostration is not completed
Hadith Q666
إِذِ الصَّلَاةُ الَّتِي لَا يُتِمُّ الْمُصَلِّي رُكُوعَهَا وَلَا سُجُودَهَا غَيْرُ مُجْزِئَةٍ عَنْهُ.
Because the prayer in which the worshipper does not perform the bowing and prostration completely is not sufficient for him.
