Is it necessary to reform oneself and adhere to all acts of worship before wearing the jilbab (esdal) for fear of falling into hypocrisy, or is it permissible to wear it while praying that Allah rectifies one's condition?

Hasten to commit to acts of worship and work on covering your body. One should not abandon acts of obedience due to shortcomings in other areas. For whoever does an atom's weight of good will see it, and whoever does an atom's weight of evil will see it.
