عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا يَتَوَارَثُ أَهْلُ مِلَّتَيْنِ شَتَّى» . رَوَاهُ أَبُو دَاوُدَ وَابْن مَاجَه وَرَوَاهُ التِّرْمِذِيّ عَن جَابر

Ibn Mas'ud said about a case where there was a grandmother and her son that she was the first grandmother to whom God’s Messenger gave a sixth which was not due to her when she had a son who was still alive. Tirmidhi and Darimi transmitted it, but Tirmidhi declared it to be a weak tradition.
