1383. It was reported from Abū Nadrāh, from Abū Sa‘eed Al-Khudrī, who said: “The Messenger of Allāh ﷺ said: ‘Search for it in the last ten of Ramaḍān. Search for it in the ninth, and the seventh, and the fifth.’” He (Abū Nadrāh) said: “I said: ‘O Abū Sa‘eed! You know your numbers better than we do!’ He said: ‘Yes.’ So he said: ‘What (do you) mean: “...the ninth, and the seventh, and the fifth?”’ He replied: ‘When twenty-one (days) have gone, then the (night) that follows it is the ‘ninth’. And when twenty-three (days) have gone, then the (night) that follows it is the ‘seventh’. And when twenty-five days have gone, then the night that follows it is the ‘fifth.’” (Sahih) Abū Dāwūd said: I don’t know, perhaps I did not hear some parts of this.
