Chapter: The virtue of Lailat Al-Qadr and the Exhortation to seek it; When it is and the most likely times to seek it
Salim reported on the authority of his father that a person saw Lailat-ul- Qadr on the 27th (of Ramadan). Thereupon Allah's Apostle ( صلی اللہ علیہ وسلم ) said: I see that your dreams agree regarding the last ten (nights of Ramadan). So seek it on an odd number (of these ten nights).
