Sahih al-Bukhari 2759
Narrated Ibn `Abbas:
Some people claim that the order in the above Verse is cancelled, by Allah, it is not cancelled, but the 
people have stopped acting on it. There are two kinds of guardians (who are in charge of the 
inheritance): One is that who inherits; such a person should give (of what he inherits to the relatives, 
the orphans and the needy, etc.), the other is that who does not inherit (e.g. the guardian of the 
orphans): such a person should speak kindly and say (to those who are present at the time of 
distribution), "I can not give it to you (as the wealth belongs to the orphans).
حَدَّثَنَا مُحَمَّدُ بْنُ الْفَضْلِ أَبُو النُّعْمَانِ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ أَبِي بِشْرٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ إِنَّ نَاسًا يَزْعُمُونَ أَنَّ هَذِهِ الآيَةَ نُسِخَتْ، وَلاَ وَاللَّهِ مَا نُسِخَتْ، وَلَكِنَّهَا مِمَّا تَهَاوَنَ النَّاسُ، هُمَا وَالِيَانِ وَالٍ يَرِثُ، وَذَاكَ الَّذِي يَرْزُقُ، وَوَالٍ لاَ يَرِثُ، فَذَاكَ الَّذِي يَقُولُ بِالْمَعْرُوفِ، يَقُولُ لاَ أَمْلِكُ لَكَ أَنْ أُعْطِيَكَ‏.‏
