Some people, when they recite (and not the astray), pronounce the letter ḍād close to the point of articulation of the letter dāl or ḍāʾ. What is the ruling?

Question:
Honorable Shaykh, may Allah grant you success. He says: We hear some people, when they recite from Surat al-Fatihah in prayer, and when they reach the words of the Exalted, "and not the astray," pronounce the letter ḍād, and the point of articulation of the letter is close to the letter dāl, and some pronounce the letter such that the ḍād becomes like the letter ḍāʾ. Is this prayer valid?

Answer:
Exaggeration in this is unnecessary. People recite, and praise be to Allah, and they emphasize the letters according to their ability and their recitation. Exaggeration in this means emphasizing the ḍād until it becomes a ṭāʾ, "and not the ṭāʾ-līn." This is exaggeration and affectation. So this is not permissible. It is not permissible to exaggerate in the recitation, the elongation, and the nasalization. It is not permissible to exaggerate in this. Rather, one might even add letters in his exaggeration, and this is not from the Qur'an. So moderation in this is the balance, and it is the good. Yes.
