Is it obligatory to spend the entire night of Laylat al-Qadr in prayer, supplication, and worship, and is there a sign before it?

Question:
On the night of Laylat al-Qadr, am I required to pray and worship the entire time, and to make supplication with the reported du'a' and others in that night without stopping, so that my supplication coincides with the time of response? And does it have a sign or indicator, as I heard that the answer will be gentle before that night? Please guide us, may Allah reward you with good. The virtue of Laylat al-Qadr and the exhortation to supplication and prayer in it

Answer:
It is a matter known from the Sunnah, and established from the Prophet (peace and blessings be upon him), . And the Mother of the Believers, Aisha (may Allah be pleased with her), asked the Messenger of Allah (peace and blessings be upon him), saying: "If I encounter Laylat al-Qadr, what should I do?" He said to her: "Say: O Allah, You are the Pardoner and You love pardon, so pardon me." Increase in this supplication and others in this night, and increase in the prayer of tahajjud in it. Allah is near and responsive. It is not obligatory to keep the entire night awake, nor to stay up without sleeping; rather, you sleep and rest, and you stand in prayer as much as is easy for you, especially standing with the imam in the mosque, in congregation. The women are to be with the congregation of women behind the rows, praying with the Muslims in the mosque in this night, and in other nights of Ramadan.
