وَعَنْ عِمْرَانَ بْنِ حُصَيْنٍ قَالَ: جَاءَ رَجُلٌ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: إِن ابْنِي مَاتَ فَمَا لِي مِنْ مِيرَاثِهِ؟ قَالَ: «لَكَ السُّدُسُ» فَلَمَّا وَلَّى دَعَاهُ قَالَ: «لَكَ سُدُسٌ آخَرُ» فَلَمَّا وَلَّى دَعَاهُ قَالَ: «إِنَّ السُّدُسَ الْآخَرَ طُعْمَةٌ» . رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَأَبُو دَاوُدَ وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ

A man came to God’s Messenger and said, “My son’s son has died, so what do I receive from his estate?” He replied, “You receive a sixth;” then when he turned away he called him and said, “You receive another sixth;” and when he turned away he called him and said, “The other sixth is an allowance ,” (It would seem, although it is not explicit, that the grandson had left two daughters who were therefore entitled to two-thirds of the estate. The grandfather was entitled only to a sixth, but was given another sixth, as a favour, presumably because there were no other heirs). Ahmad, Tirmidhi and Abu Dawud transmitted it, Tirmidhi saying this is a hasan sahih tradition.
