كُنْ كَمَا أَمْكَنَكَ
Be as you are able to be.
The independent device mā lā yastaḥīlu bi-l-inʿikās is also called qalb. Its letters can be read in reverse sequence without changing the resulting letter pattern; spaces and vowel marks are not the primary test.
“Kun kamā amkanak” provides a classic reversible sequence. Unlike letter-transposition jinas, the concern is the reversibility of an expression as a whole.
