Sahih Muslim
حَدَّثَنَا أَحْمَدُ بْنُ عَبْدِ اللَّهِ بْنِ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا أَبُو إِسْحَاقَ، قَالَ رَأَيْتُ رَجُلاً سَأَلَ الأَسْوَدَ بْنَ يَزِيدَ وَهُوَ يُعَلِّمُ الْقُرْآنَ فِي الْمَسْجِدِ فَقَالَ كَيْفَ تَقْرَأُ هَذِهِ الآيَةَ فَهَلْ مِنْ مُدَّكِرٍ أَدَالاً أَمْ ذَالاً قَالَ بَلْ دَالاً سَمِعْتُ عَبْدَ اللَّهِ بْنَ مَسْعُودٍ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مُدَّكِرٍ " . دَالاً .
Abu Ishaq reported: I saw a man asking Aswad b. Yazid who taught the Qur'an in the mosque: How do you recite the verse (fahal min muddakir) whether (the word muddakir) Is with (d) or (dh)? He (Aswad) said: It was with (d). I heard Abdullah b. Mas'ud saying that he had heard the Messenger of Allah (ﷺ) reciting (muddakir) with (d).
