Here’s 4 Hadiths on Laylatul Qadr with some commentary

Abu Hurairah (May Allah be pleased with him) reported: The Prophet (PBUH) said, “Whosoever performs Qiyam during Lailat-ul-Qadr (Night of Decree), with Faith and being hopeful of Allah’s reward, will have his former sins forgiven.”
[Al-Bukhari and Muslim].

Commentary: Qiyam here means what keeps one awake to one’s capacity and for worship and makes one perform Nawafil, impels one to beg pardon for sins from Allah, urges one to praise Him. Specially, if a person performs `Isha prayer and Fajr prayer in congregation, he will hopefully attain all those distinctions which are mentioned in this Hadith.
1190. Narrated ‘Ubada bin As-Samit:

`Aishah (May Allah be pleased with her) reported: The Messenger of Allah (PBUH) used to seclude himself (in the mosque) during the last ten nights of Ramadan. He would say, “Search for Lailat-ul-Qadr (Night of Decree) in the last ten nights of Ramadan.” [Al-Bukhari and Muslim].

1192. `Aishah (May Allah be pleased with her) reported: The Messenger of Allah (PBUH) used to observe I`tikaf in the last ten days of Ramadan and say, “Seek Lailat-ul-Qadr (Night of Decree) in the odd nights out of the last ten nights of Ramadan.” [Al-Bukhari].

Commentary: We learn from this Hadith that Lailat-ul-Qadr occurs in any of the five odd nights – 21st, 23rd, 25th, 27th and 29th – of the last ten nights of Ramadan. Its exact date has not been revealed for the reason that people keep themselves awake for prayer for a larger number of nights. Had its date been fixed, people would have kept awake for prayer only on that night. There is a general belief among the scholars that it is fixed, on the 27th night of Ramadan.

1194. `Aishah (May Allah be pleased with her) reported: The Messenger of Allah (PBUH) used to strive more in worship during Ramadan than he strove in any other time of the year; and he would devote himself more (in the worship of Allah) in the last ten nights of Ramadan than he strove in earlier part of the month. [Muslim].

Commentary: We learn from this Hadith that:

1. One should concentrate more on prayers and worship on the last ten nights of Ramadan than the first twenty nights, in the same way as one should do more worship in Ramadan than in the other months.

2. One should keep oneself awake for prayer, worship and glorification of Allah in the last ten nights of Ramadan so that one can attain the blessings of Lailat-ul-Qadr.

3. One should also persuade his family members to keep themselves awake for prayer and worship in the last ten odd nights of Ramadan so that they can also make efforts to please Allah.

4. I`tikaf (seclusion in the mosque for prayers) in the last ten days of Ramadan is also a meritorious act for its being a practice of the Prophet (PBUH).
