Is the prayer of Qiyam al-Layl accepted from a woman who conceals it from her husband due to his objection to it, knowing that she does not fall short in her marital and family duties?

If the wife's night prayer does not prevent her husband from enjoying her company or cause her to neglect her duties, then he has no right to forbid her from it. However, if it does prevent him from some enjoyment, she should not perform it except with his permission. She should explain to him the virtue of night prayer with gentleness and kindness, and strive to reconcile between her worship and pleasing her husband.
