The sign of Laylat al-Qadr is that the sun rises on the following morning with no visible rays. Laylat al-Qadr may be seen with the eye for the one whom Allah helps to see it. That is by seeing its signs.

Among the adhkar that can be recited after prayer are the following: 1. Astaghfirullah 3 times 2. Allahumma anta al-salam wa minka al-salam tabarakta ya dhal-jalali wa’l-ikram 3. Reciting Ayat al-Kursiy silently, 4. Reciting Qul Huwa Allahu Ahad, Qul a'udhu bi Rabbi’l-Falaq and Qul a’udhu bi Rabbi’l-Nas.

There is nothing wrong with a woman who is Junub cooking, looking after her house, taking care of her children or fulfilling any other needs.

It is permissible for one who is Junub to go to sleep before doing Ghusl, then wake up to do Ghusl before praying Fajr. But it is better for him to do Wudu before going to sleep, and if he does Ghusl that is best.
