Question: Some of the Muslims have taken the 27th night of Ramadhaan as Laylatul-Qadar. Is their any basis for this specification and is there any evidence for this?
Response: Yes, there is basis for this specification and that is that the night of the 27th of Ramadhaan is mentioned in the hadeeth, in Saheeh Muslim, on the authority of ‘Ubayy Ibn Ka’b (radhi-yAllaahu ‘anhu).
However, the overwhelming opinion of the people of knowledge, from the forty or more opinions, is that Laylatul-Qadar is in the last ten nights, and specifically in the last seven of those nights. So, it is possible that it could be on the 27th night, the 25th, the 26th or even the 24th night [and so on].
Because of this, it is befitting for [each] person to exert [himself in worship] during all the nights such that he does not deny himself the excellence of them and the reward [to be gained] in them.
Allaah (Subhaanahu wa Ta’aala) says:
{We sent it (this Qur.aan) down on a blessed night [(i.e. Laylatul-Qadar) in the month of Ramadaan]. Verily, We are ever warning [mankind that Our Torment will reach those who disbelieve in Our Oneness of Lordship and in Our Oneness of worship]}, [Soorah ad-Dukhkhaan, Aayah 3]
And He (Subhaanahu wa Ta’aala) also said:
{Verily! We have sent it (this Qur.aan) down in the night of al-Qadar. And what will make you know what the night of al-Qadar is? The night of al-Qadar is better than a thousand months (i.e. worshiping Allaah in that night is better than worshiping Him a thousand months, i.e. 83 years and 4 months). Therein descend the angels and the Rooh (Jibreel) by Allaah’s Permission with all Decrees. Peace! (all that night, there is Peace and Goodness from Allaah to His believing slaves) until the appearance of dawn}, [Soorah al-Qadar, Aayaat 1-5]
