Book Number: 004 / Hadith Number: 764
Abu Salama reported: Abu Huraira led prayer for them and recited takbir when he bent and raised himself (in ruku' and sujud) and after completing (the prayer) he said: By Allah I say prayer which has the best resemblance with the prayer of the Holy Prophet (may peace be upon him) amongst you.
