Conveying and teaching religion to the people, and correcting any shortcomings, is obligatory upon every Muslim, commensurate with his level of knowledge and ability. The Tabi‘in used to keep close to the companions of the Prophet (blessings and peace of Allah be upon him) in order to learn from their knowledge, and if they made a mistake, the Sahabah (may Allah be pleased with them) would correct them. In this hadith, the Tabi‘i Mutarrif ibn ‘Abdillah ibn ash-Shikhkhir narrates that he and ‘Imran ibn Husayn (may Allah be pleased with him) prayed behind ‘Ali ibn Abi Talib (may Allah be pleased with him) in Basra, in Iraq. ‘Imran (may Allah be pleased with him) said to those around him, after the prayer ended: This man – meaning ‘Ali ibn Abi Talib (may Allah be pleased with him) – reminded us of the prayer that we used to pray with the Prophet (blessings and peace of Allah be upon him). And he stated that he used to say takbir every time he lowered his head and raised it during the prayer. So he said takbir every time he went down, bowing and prostrating, and every time he rose from both. But he used to say when rising from bowing: “Sami‘a Allahu limanhamidah, Rabbanawalaka al-hamd (Allah hears those who praise Him; our Lord, to You be praise),” and similar phrases that have been narrated for this point in the prayer, and he did not say takbir. This is an exception from takbir, but what is said here refers to what is most often the case, so takbir is mentioned because this is what is said in most of the movements of the prayer. ‘Imran (may Allah be pleased with him) said that because that emphasizes how the Sahabah (may Allah be pleased with them) used to pray. This hadith describes the prayer of the Prophet (blessings and peace of Allah be upon him). It also highlights the keenness of the Sahabah to follow the Sunnah of the Messenger of Allah (blessings and peace of Allah be upon him). .
