Is it permissible to write "alle ef mokopeho" instead of "أحبكم في الله" (I love you for the sake of Allah) as a joke, with the intention of having the words read backward?

Love for the sake of Allah is one of the strongest bonds of faith and a means of salvation on the Day of Resurrection. It has great virtues, including: tasting the sweetness of faith, and being among those whom Allah will shade on the Day of Resurrection, for those who love each other for His sake. It is desirable to inform the one you love that you love him for the sake of Allah. This legitimate expression must be protected from mockery and jest. It is permissible to express it in foreign languages or to write it using foreign characters.
