Is the assimilation (Idgham) applied to the silent "noon," as in "man ya'mal" (مَنْ يَعْمَل), where the "noon" is assimilated into the "yaa" and they become like a doubled "yaa," in contexts other than the Qur'an?

The rules of tajwid (elocution) are specific to the recitation of the Holy Quran, and therefore, they should not be applied to other forms of speech such as Hadith, supplications (du'a), sermons, poetry, or ordinary conversation. Ibn Mas'ud said, "This is like the hurried recitation of poetry." The Prophet Muhammad (peace be upon him) used to speak slowly when narrating his Hadith; he would not rattle off Hadith as we do, but rather he would speak with clear, distinct words that those who sat with him could memorize. Some later scholars mentioned that one of the implications of the noble verse: "And indeed, there is among them a party who alter the Scripture with their tongues so that you may think it is from the Scripture," is that a person recites something other than the Quran in the manner of Quranic recitation, such as Hadith or the words of scholars. Thus, it is not permissible to chant non-Quranic speech in the manner of Quranic recitation, especially among the common people who distinguish only by melodies and recitation. In conclusion, the rules of tajwid must be exclusive to the words of Allah Almighty, and nothing else.
