What is the ruling on the the prayer of someone who, throughout his life, said in the Tashahhud: "Peace be upon us and upon God's righteous servants" instead of "Peace be upon us and upon the righteous servants of God"?

The worshiper's saying "Peace be upon us and upon our righteous servants" instead of "upon the righteous servants of Allah" is an error that changes the meaning by attributing the servants to the worshiper. However, they are excused if this occurred out of ignorance and without intent to violate, based on the verse: "Our Lord, do not impose blame upon us if we forget or make a mistake." And if the prayer time has elapsed, they are not obligated to repeat it, because ignorance and forgetfulness are among the impediments to accountability in relation to Allah.
