Idgham of the Nūn in the phrase “I bear witness that there is no god but Allah”

Question:
Is there a difference in the idgham of the phrase “I bear witness that there is no god but Allah,” or not?

Answer:
It is necessary to clarify: in “I bear witness that there is no,” the nūn is idgham’d into the lām. The phrase must be clear: “I bear witness that there is no,” not “I bear witness that no.” This is the method of the Arabs and the reciters: the quiescent nūn is idgham’d into the lām that follows it, just as it is idgham’d into the yā’ that follows it, and into the mīm that follows it. There are six letters into which the quiescent nūn is idgham’d, as in “and upon his family and his companions and whoever follows them in peace.”
