That he should not divorce her all of his days: That one who puts out a bad name about his wife and is found to be a liar with his words is prevented from divorcing her forever. And about this is it stated (Deuteronomy 22:19), “he may not send her away all of his days.”
I have written about the roots of this commandment and how is the putting out of a bad name and a few of its laws in its positive commandment in this Order (Sefer HaChinukh 553), as is my custom — and take it from there.
שֶׁלֹּא יְגָרְשֶׁנָּה כָּל יָמָיו – שֶׁנִּמְנַע מוֹצִיא שֵׁם רַע עַל אִשְׁתּוֹ וְנִמְצָא שַׁקְרָן בִּדְבָרָיו שֶׁלֹּא לְגָרְשָׁהּ לְעוֹלָם, וְעַל זֶה נֶאֱמַר (דברים כב יט) לֹא יוּכַל לְשַׁלְּחָהּ כָּל יָמָיו.

מִשָּׁרְשֵׁי הַמִּצְוָה. וְכֵיצַד הוֹצָאַת שֵׁם רַע וּקְצָת דִּינֶיהָ כְּמִנְהָגִי כָּתַבְתִּי בְּמִצְוַת עֲשֵׂה שֶׁלּוֹ שֶׁבְּסֵדֶר זֶה (מצוה תקנג), וְקָחֶנּוּ מִשָּׁם.
