It was narrated from Anas bin Malik that the Messenger of Allah ﷺ 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 ﷺ " الْمَحْرُومُ مَنْ حُرِمَ وَصِيَّتَهُ " .
