Sunan Abi Dawud Book 35, Hadith 15
The Prophet (ﷺ) said: If a woman uses perfume and passes the people so that they may get its odour, she is so-and-so, meaning severe remarks.
If anyone is presented some perfume, he should not return it, for it is a thing of good fragrance and light to bear.
A woman met him and he found the odour of perfume in her. Her clothes were fluttering in the air. He said: O maid-servant of the Almighty, are you coming from the mosque? She replied: Yes. He said: For it did you use perfume? She replied: Yes. He said: I heard my beloved AbulQasim (ﷺ) say: The prayer of a woman who uses perfume for this mosque is not accepted until she returns and takes a bath like that of sexual defilement (perfectly).
Abu Dawud said: Al-i'sar means dust.
