Signs of Laylatul-Qadr

Narrated Aaisha رضي الله عنها :
She said: “O Messenger of Allaah! If I find it (The Night Of Decree), with what should I supplicate?”  Heصلّى اللَّهُ عليه وسلّم  said:

اللْهُمَّ إِنَّكَ عَفُوٌّ تُحِبُّ الْعَفْوَ فَاعْفُ عَنِّي

(( Say: Allaahumma innaka ‘afuwun tuhibbul-‘afwa fa’fu ‘annee.))
“O Allaah! Verily, you are the Oft-Pardoning, You love to pardon, so pardon me.”
[Ahmad]

Question: What are the signs of Laylatul-Qadar (the night of power)?
Response: From amongst the signs of Laylatul-Qadar is that it is a calm night and the believer’s heart is delighted and at peace with it, and he becomes active in doing good actions, and the sun on the following morning rises clearly without any rays.
