"One" is a cardinal number. Its Arabic equivalent depends on the context (how it will be used in a sentence). You did not provide context for the word "one." Each of the options I suggested will work in a specific kind of context.

The Arabic sentence you posted in the space provided for context has nothing to do with the word "one." Its literal translation is:

Islamic law is justice and compassion, balance, spirituality, and peace of mind.

The intended meaning is probably:

Islamic law is characterized by justice compassion, and spriituality. It it provides peace of mind.

Neither the word "one" nor the Arabic sentence has anything to do with textile.

The last word of the sentence seems out of place rather than an item in the preceding series. Unlike the other items, it has the definite prefix \"AL-\" attached to it. It may be part of the next sentence.
