Narrated AbuHurayrah:

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.

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، حَدَّثَنَا سُفْيَانُ، عَنْ عَاصِمِ بْنِ عُبَيْدِ اللَّهِ، عَنْ عُبَيْدِ اللَّهِ، مَوْلَى أَبِي رُهْمٍ عَنْ أَبِي هُرَيْرَةَ، قَالَ لَقِيَتْهُ امْرَأَةٌ وَجَدَ مِنْهَا رِيحَ الطِّيبِ يُنْفَحُ وَلِذَيْلِهَا إِعْصَارٌ فَقَالَ يَا أَمَةَ الْجَبَّارِ جِئْتِ مِنَ الْمَسْجِدِ قَالَتْ نَعَمْ . قَالَ وَلَهُ تَطَيَّبْتِ قَالَتْ نَعَمْ . قَالَ إِنِّي سَمِعْتُ حِبِّي أَبَا الْقَاسِمِ ﷺ يَقُولُ " لاَ تُقْبَلُ صَلاَةٌ لاِمْرَأَةٍ تَطَيَّبَتْ لِهَذَا الْمَسْجِدِ حَتَّى تَرْجِعَ فَتَغْتَسِلَ غُسْلَهَا مِنَ الْجَنَابَةِ " . قَالَ أَبُو دَاوُدَ الإِعْصَارُ غُبَارٌ .
