Narrated 'Ubada bin As-Samit:The Prophet (ﷺ) came out to inform us about the Night of Qadr but two Muslims were quarreling with each other. So, the Prophet (ﷺ) said, "I came out to inform you about the Night of Qadr but such-and-such persons were quarreling, so the news about it had been taken away; yet that might be for your own good, so search for it on the 29th, 27th and 25th (of Ramadan)
