Is it possible to see Laylat al-Qadr with the naked eye, what are the signs of seeing it, how did the Prophet (PBUH) and the Companions see it, and does one attain its reward if they did not see it?

Laylat al-Qadr can be seen with the eye through observing its signs, such as the sun rising on its morning without any rays. Not seeing it does not prevent one from attaining its virtue for whoever observes it in prayer with faith and anticipation of reward. The most preponderant opinion is that it shifts among the last ten nights of Ramadan, especially on the odd nights, with the twenty-seventh night being the most emphasized of these nights. Whoever strives in worship throughout all of the last ten nights will have attained it and earned its reward.
