"I said to Ata: 'I heard that you pray twelve rak'ahs before Jumu'ah. What did you hear concerning that?' He said: 'I was told that Umm Habibah bin Abi Sufyan said: "I heard the Messenger of Allah (ﷺ) say: 'Whoever prays twelve rak'ahs during the day and night, apart from the prescribed prayers, Allah (SWT), the Mighty and Sublime, will build for him a house in Paradise.'"
Sunan an-Nasa'i Book 20, Hadith 200
