(The book) ‘Al Kafi’ – From Ali, from his father, from Al Nowfaly, from Al Sakuny, ‘From Abu Abdullah -asws having said: ‘Rasool-Allah -saww said: ‘Above every one with righteousness, there is a righteousness, to the extent the man is killed in the Way of Allah -azwj , so there isn’t any righteousness above it; and above every disowning there is a disowning, to the extent the man kills one of his parents. When he does that, there isn’t any disowning above it’’.
(The book) ‘Kitab Al Imamah Wa Al Tabsira’ of Ali Bin Baubawyh, from Sahl Bin Ahmad, from Muhammad Bin Muhammad Bin Al Ash’as, ‘From Musa Bin Ismail son of Musa -asws Bin Ja’far -asws – similar to it, except that in it is: ‘For it is an eraser (of sins)’’. [8] وَ بِهَذَا الْإِسْنَادِ قَالَ قَالَ رَسُولُ اللَّهِ ص إِنَّ فَوْقَ كُلِّ بِرٍّ بِرّاً حَتَّى يُقْتَلَ الرَّجُلُ شَهِيداً فِي سَبِيلِ اللَّهِ وَ فَوْقَ كُلِّ عُقُوقٍ عُقُوقاً حَتَّى يَقْتُلَ الرَّجُلُ أَحَدَ وَالِدَيْهِ.
And by this chain, ‘He -asws said: ‘Rasool-Allah -saww said: ‘Above every (act of) righteousness there is (an act of) righteousness, until the man is killed as a martyr in the Way of Allah -azwj ; and above every disowning there is a disowning, until the man kills one of his parents’’.
