I asked this question (Fatwa: 89050) but you did not answer it in full most of it you did but on the Day of Judgement would this sin come out be told to the husband by Allaah or would it be concealed I need to know this urgently from your knowledge.

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.

We do not know any text from the Qur'an or the Sunnah which indicates that if a woman commits adultery Allaah will inform her husband about it on the Day of Judgement. However, Allaah may ask a person to confirm some of his sins, and inform him about them (the sins). Allaah says (which means): {The Day every soul will find what it has done of good present [before it] and what it has done of evil present before it, it will wish that there were a great distance between itself and that evil.}[3:30].

 Allaah knows best.
