When a man puts another forward: does he begin the recitation again or recite from where the other stopped?

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: When the Prophet (peace and blessings be upon him), in his final illness, came to Sayyiduna Abu Bakr (may Allah be pleased with him) during the prayer, he recited from the point Sayyiduna Abu Bakr (may Allah be pleased with him) had reached.

Amir said: If a man's ablution breaks during the prayer and he puts someone else forward to lead, then his recitation suffices for him if he had recited, and his takbir if he had said the takbir.

Al-Hasan said concerning the person whom the imam puts forward: If he wishes, he may recite from where the imam had reached, and if he wishes, he may recite from some other surah.
