Saeed Ibn al Musayyib would say, the one who prays Maghrib and Esha in jamaat has caught Laylatul Qadr! So, strive to pray them in jamaat!
“I asked Ubayy ibn Ka`b, saying: Your brother Ibn Mas`ood says: Whoever stands in (Night) Prayer throughout the whole year will attain Laylatul-Qadr (The Night of Decree). So, he said: “May Allaah have mercy upon him! He intended that the people should not just rely (upon a single night). Indeed, he knew that it was in Ramadaan; and that it is in the last ten; and that it was the twenty seventh night.” Then he swore an oath, without exception that it was the twenty seventh night.” So, I said:” O Abul-Mundhir! Upon what basis do you say that?” He said: “Based upon the sign which Allaah’s Messenger (saw) informed us of: that it [i.e. the sun] will rise on that day having no rays.”
Imaam an-Nawawee (rh) said in his explanation of Saheeh Muslim: “…al-Qaadee `Iyaad said:
It is said that the meaning of its having no rays is that this was just a distinctive sign which Allaah -the Most High – made for it [that year]. He said: Or it is otherwise said: Rather it is on account of the great number of Angels coming and going on its night; and their descending to the earth, and their ascending, with that which they descended with. So, their wings and their subtle/ethereal bodies screen the light of the sun and its rays, and Allaah knows best.”
Imaam Aboo Daawood (rh) reported the hadeeth (The Book of the Prayer: Chapter 319: What occurs regarding the Night of Decree), (no. 1378), with the wording:
“…On the morning following that night the sun enters the morning like a brass dish, having no rays, until it has risen higher.”
[Declared “hasan saheeh” by Shaikh al-Albaanee -rahimahullaah.]
Imaam Ibn Khuzaymah (rh) reported in his Saheeh (no. 2192): “Bundaar narrated to us: Aboo `Aamir narrated to me: Zam`ah narrated to us: from Salamah – he is Ibn Wahraam-: from `Ikrimah: from Ibn `Abbaas: from the Prophet (saw) that he said regarding the Night of Decree:
“It is a pleasant night, being neither hot nor cold. The sun enters the morning of its day being red and weak.”
Some narrations mention that Laylatul Qadr is like pure and glowing as if there was a bright Moon as mentioned by Ibn Katheer (rh) as mentioned in his tafseer and Allah Knows best.
What do we say about which night Laylatul Qadr is?
Laylatul Qadr can be in any of the last 10 nights of Ramadan. Even more specific than that, it can be in the odd numbered nights.
Ubayy Ibn Ka’b (ra) from the Sahaabah swore by Allah that it’s on the 27th night and this is in the saheeh. This is why people emphasis this night.
Can there be a variable? Is it based on the lunar calendar?
The Islamic month (lunar calendar) is 29 or 30 days. After the 30th day it is automatically the next month.
So, when it says the “odd nights” that’s put into context by sheikh ul Islam (rh). His view to combine between why the Sahaabah mentioned so many different nights is that:
It changes every year
In addition –
We don’t know if the month will be 29/30 days! So, in reality it’s any of the last ten nights.
Ibn Hajr (rh) mentions a large amount of views in fath ul Bari on when it could be and sheikh ul Islam’s view seems strong.
Allah Knows Best
Du’a in sujood and du’a after tashahud should be prolonged in these nights. If you don’t know Arabic then any du’as you have memorised, the du’a of Laylatul Qadr, istighfar and anything else you know should be used.
