Ibn Juraij said:

"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 (Subhanahu-wa-Taala), the Mighty and Sublime, will build for him a house in Paradise.'"

أَخْبَرَنِي إِبْرَاهِيمُ بْنُ الْحَسَنِ، قَالَ حَدَّثَنَا حَجَّاجُ بْنُ مُحَمَّدٍ، قَالَ قَالَ ابْنُ جُرَيْجٍ قُلْتُ لِعَطَاءٍ بَلَغَنِي أَنَّكَ تَرْكَعُ قَبْلَ الْجُمُعَةِ اثْنَتَىْ عَشْرَةَ رَكْعَةً مَا بَلَغَكَ فِي ذَلِكَ قَالَ أَخْبَرَتْ أُمُّ حَبِيبَةَ عَنْبَسَةَ بْنَ أَبِي سُفْيَانَ أَنَّ النَّبِيَّ ﷺ قَالَ " مَنْ رَكَعَ اثْنَتَىْ عَشْرَةَ رَكْعَةً فِي الْيَوْمِ وَاللَّيْلَةِ سِوَى الْمَكْتُوبَةِ بَنَى اللَّهُ عَزَّ وَجَلَّ لَهُ بَيْتًا فِي الْجَنَّةِ " .
