Musannaf Ibn Abi Shayba 3:3520

Waki’ narrated to us, he said: Isra’il narrated to us, from Jabir, from ‘Amir, regarding a man who broke his wudu during prayer, so he took a man by the hand and brought him forward. He said: His recitation suffices him if he had recited, and his takbir suffices him if he had performed the takbir.
