Narrated from Zirr with reference to Ubayy bin Ka'b (may Allah be pleased with him) that once the companions (may Allah be pleased with them) began discussing Laylat al-Qadr. Ubayy (may Allah be pleased with him) said, "By Him besides whom there is no deity, I have the most knowledge about this night. The Prophet (peace and blessings be upon him) informed us about the night, and it is the twenty-seventh night of Ramadan. Its sign is that after the night passes, the next day when the sun rises, it appears to be spinning and it has no rays." Salamah bin Kuhayl says that according to Zirr, he has been searching for it continuously for three years from the beginning to the end of Ramadan, and he has always seen the sun rising in this state on the morning of the twenty-seventh night.
