Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "When the imam is sitting in the final tashahhud after reciting the last rak'ah, and someone following him loses his wudu before the imam says salam, then that person's prayer will be considered complete." The narrator of this narration, Abdur Rahman bin Ziyad, is weak; he has not been regarded as reliable.
