Is informing a female friend about a sin—for the purpose of seeking advice and returning to righteousness—considered an open declaration of sin (mujāharah bi al-dhanb) which is prohibited? And does Allah forgive one who repents from openly declaring a sin?

The questioner erred by committing what violates the law of Allah, and she must make sincere repentance accompanied by remorse and a firm resolve not to return to the sin. And her informing her friend is not considered blameworthy open sin (mujāharah) if it is for the purpose of benefiting from advice and guidance. Scholars have mentioned that informing about a sin with the intention of seeking a fatwa or asking for help is not open sin, unlike informing about it openly and mockingly.
