The Obligation To Perform The Salat (Prayers)
Sunan Abi Dawud
حَدَّثَنَا سُلَيْمَانُ بْنُ دَاوُدَ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ الْمَدَنِيُّ، عَنْ أَبِي سُهَيْلٍ، نَافِعِ بْنِ مَالِكِ بْنِ أَبِي عَامِرٍ بِإِسْنَادِهِ بِهَذَا الْحَدِيثِ قَالَ " أَفْلَحَ وَأَبِيهِ إِنْ صَدَقَ دَخَلَ الْجَنَّةَ وَأَبِيهِ إِنْ صَدَقَ " .
This tradition has also been reported by Abu Suhail Nafi' b. Malik b. Abi 'Amir through a different chain of narrators. It adds: He will be successful, by his father, if he speaks the truth; he will enter Paradise, by his father, if he speaks the truth.
