It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when the Prophet (peace and blessings be upon him) became ill, he ordered Sayyiduna Abu Bakr (may Allah be pleased with him) to lead the people in prayer. Then, when the Prophet (peace and blessings be upon him) felt some relief in his illness, he came out. When Sayyiduna Abu Bakr (may Allah be pleased with him) sensed the presence of the Prophet (peace and blessings be upon him), he intended to step back, but the Prophet (peace and blessings be upon him) signaled to him and sat down at his left side, and began reciting from where Sayyiduna Abu Bakr (may Allah be pleased with him) had left off.
