It was narrated from Abu Hurairah that the Prophet ( صلی اللہ علیہ وسلم ) said:`“Whoever applies kohl, let him do it an odd number of times. Whoever does that has done well, and whoever does not, it does not matter.”

A similar report was narrated by 'Abdul-Malik bin As-Sabbah with a similar chain, with the additional words: "Whoever applies kohl to his eyes, let him add it an odd number of times. Whoever does that has done well, and whoever does not, there is no harm in it. And whoever dislodges (a particle of food from between the teeth) by dislodging it with his tongue, let him swallow it."
