It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) rode a horse, then fell from it, and his right side was grazed. So the Prophet (peace and blessings of Allah be upon him) performed the prayer sitting, and we also performed the prayer sitting behind him. Then when the Prophet (peace and blessings of Allah be upon him) finished the prayer, he said: "The Imam is appointed so that he may be followed. So when the Imam prays standing, you should also pray standing, and when the Imam bows (in ruku‘), you should also bow, and when the Imam raises his head, you should also raise your heads, and when the Imam says «سَمِعَ اللّٰهُ لِمَنْ حَمِدَهُ» , you should say «رَبَّنَا وَلَكَ الْحَمْدُ» , and when the Imam prays sitting, you should also pray sitting."

It is narrated from Umm al-Mu'mineen Sayyidah Aisha Siddiqa (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) performed prayer while sitting due to illness, and the people began to pray standing. Then the Prophet (peace and blessings be upon him) gestured to them to sit down. When he finished the prayer, he said: "The Imam is appointed so that he may be followed; therefore, when the Imam bows, you should also bow, and when the Imam raises his head, you should also raise your heads, and when the Imam performs prayer sitting, you should also perform prayer sitting."

It is narrated from Sayyiduna Urwah bin Zubair (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) came out during his illness of death, so he came to the mosque and found Sayyiduna Abu Bakr as-Siddiq (may Allah be pleased with him) leading the people in prayer. Sayyiduna Abu Bakr as-Siddiq (may Allah be pleased with him) wanted to step back, but the Prophet (peace and blessings of Allah be upon him) gestured to him, "Stay in your place." The Prophet (peace and blessings of Allah be upon him) then sat beside Sayyiduna Abu Bakr as-Siddiq (may Allah be pleased with him), so Sayyiduna as-Siddiq al-Akbar (may Allah be pleased with him) would follow the prayer of the Messenger of Allah (peace and blessings of Allah be upon him), and the people would follow the prayer of Sayyiduna as-Siddiq al-Akbar (may Allah be pleased with him).
