259 - وَبِإِسْنادِهِ عَنْ عَلِيِ a.sُ قالَ: قالَالنَّبِي صَلَّى اللهُ عَلَيْهِ وَآلِهِ: إِنّي تارِكٌ فِيكُم الثَّقَلَيْنِ: كِتاب اللَّه وَعِتْرَتِي، وَلَنْ يَفتَرِقا حَتّى يَرِدا عَلَي الحَوضَ.

31-259 According to the same documentation, on the authority of Ali , the Prophet (S) said, “I leave two important things with you - God’s Book and my ‘Itra. They will not separate from each other until they return to me at the Pool.”
