Sunan Ibn Majah, Hadith 2700 ⓘ
It was narrated from Anas bin Malik that the Messenger of Allah said: “The one who is deprived is the one who is deprived of a will.”
حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، حَدَّثَنَا دُرُسْتُ بْنُ زِيَادٍ، حَدَّثَنَا يَزِيدُ الرَّقَاشِيُّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الْمَحْرُومُ مَنْ حُرِمَ وَصِيَّتَهُ " .
