What is the period within which the Qur'an should be completed so that it is not considered abandoned?

Question:
The questioner will ask: Is it mentioned in the hadith of the Prophet (peace and blessings be upon him) that whoever does not complete the Qur'an in forty days has abandoned it? And what is the maximum period for leaving the Qur'an?

Answer:
No, we do not know of any evidence for this, but it is better for a person to strive to read the Qur'an and to be diligent in its recitation. As for calling someone one who has abandoned it if a month, ten days, or forty days have passed, there is no evidence for that. However, it is recommended for the believer to increase his recitation of the Qur'an, because there is great good in its recitation. The Prophet (peace and blessings be upon him) said to Abdullah ibn Amr: Read it in a month, until he said to him: If it is easy for him to read it every month, or every twenty days, or every forty days, that is all good. He should strive to read it, and if it is easy for him to do so every seven days, that is good. Yes.
