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).

Is there anyone among you who recites according to the recitation of Abdullah? I said: Yes, it is I. He again said: How did you hear 'Abdullah reciting this verse: (wa'l-lail-i-idha yaghsha = when the night covers)? He ('Alqama) said: I heard him reciting it (like this) (wa'l-lail-i-idha yaghsha) wa-dhakar wal untha = when the night covers and the males and the females). Upon this he said: By Allah, I heard the Messenger of Allah (ﷺ) reciting in this way, but they (the Muslims of Syria) desire us to recite: (wa ma khalaqa), but I do not yield to their desire.
