Does what Al-Tabari said in interpreting the verse, "{And abide in your houses}," when he favored the recitation with a kasra on the letter qaf, mean an error in the well-known recitation with a fatḥa on the letter qaf, and is this considered disbelief?

Al-Tabari's statement in interpreting the verse does not fault whoever reads (وَقَرْنَ) with an open "Qaf" (fatha), but rather mentions that it is the reading of the people of Madinah and some Kufans.

He prefers the reading (وَقِرْنَ) with a

kasra on the "Qaf" because it is the reading of the majority, and because it is derived from "waqar" (dignity/composure).

Both readings are valid.

Al-Qurtubi mentioned that the majority read (وَقِرْنَ) with a kasra on the "Qaf", and 'Asim and Nafi' read it with a fatha.

The meaning of the verse is a command to remain in the home, and although the address is to the wives of the Prophet (peace be upon him), others are included in its meaning.

Ibn Juzayy said that the reading with a kasra could be from "waqar" (dignity/composure) or from "qarar" (settling/staying), and the reading with a fatha is from "qarar" (settling/staying).
