What is the ruling on a spelling error in writing in the Arabic language if it is not intended to mock the language?

Error is forgiven for the Ummah, whether concerning what is obligatory or forbidden, in accordance with His, the Almighty's, saying: "And there is no blame upon you for that in which you have erred," and His, peace and blessings be upon him, saying: "Allah said: 'I have done so,'" when reciting: "Our Lord, do not impose blame upon us if we forget or make a mistake." The obligatory orthography to follow is that of the Holy Quran. As for the orthography of the Arabic language, it is conventional and not obligatory, and there is no sin in changing it, whether by mistake or intentionally, as long as the intentional change does not lead to something forbidden.
