أَخْبَرَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا حَسَنٌ، عَنْ أَبِي سَهْلٍ، عَنْ الشَّعْبِيِّ فِي ابْنِ الْمُلَاعَنَةِ: تَرَكَ ابْنَ أَخٍ وَجَدًّا، قَالَ: "الْمَالُ لِابْنِ الْأَخِ".
It is narrated from Imam Sha'bi, may Allah have mercy on him, regarding the son of the mal'ana: Whoever leaves behind a nephew and a grandfather (or maternal grandfather), he said that all the wealth will go to the nephew. (Because after li'an, the relation to the grandfather is not valid, therefore he will not be an heir. And Allah knows best.)
