Hadith text
Narrated Mutarrif bin `Abdullah:`Imran bin Husain and I offered the prayer behind `Ali bin Abi Talib. When `Ali prostrated, he said the Takbir, when he raised his head, he said the Takbir and when he got up for the third rak`a he said the Takbir. On completion of the prayer `Imran took my hand and said, "This (i.e. `Ali) made me remember the prayer of Muhammad" Or he said, "He led us in a prayer like that of Muhammad
Mutarrif bin Abdullah bataate hain ke main aur Imran bin Husain ne Ali bin Abi Talib ke peechhe namaz padhi. Jab Ali sajda karte, Takbir kehte, jab sar utha te, Takbir kehte, aur teesri rakat ke liye uthte waqt bhi Takbir kehte. Namaz mukammal hone par Imran ne mera haath pakda aur kaha: "Isne (Ali ne) mujhe Muhammad ki namaz yaad dilai," ya kaha: "Unhone humari imamat Muhammad jaisi ki."
