What is the interpretation of the difference between the narrations of Hafs and Qalun for the Holy Quran, and what is the interpretation of the difference between the word "litundhir" (to warn) and "liyundhir" (to warn) in Surat Ya-Sin between them?

"Linudhir" has two mutawatir (concurrently transmitted) readings: one with a 'ta' (ت) and one with a 'ya' (ي).

Based on the 'ta' reading: The address is to the Prophet, peace be upon him, meaning: "So that you, O Muhammad, may warn whoever is alive."

Based on the 'ya' reading: The meaning is that Allah Almighty warns, or that the aforementioned Quran warns.

The intended meaning: It is an allusion to the disbelievers who turn away from the Quran's proofs, likening them to the dead, while whoever is alive in their heart and faith benefits from the warning.
