Narrated Ibn ‘Umar:
Some men amongst the companions of the Prophet were shown in
…their dreams that the night of Qadr was in the last seven nights of
Ramadan. Allah’s Apostle said,”It seems that all your dreams agree
that(the Night of Qadr) is in the last seven nights, and whoever
wants to search for it(i.e. the Night of Qadr) should search in
the last seven (nights of Ramadan).
