The Prophet ﷺ said: If any woman asks her husband for divorce without some strong reason, the odour of Paradise will be forbidden to her. (Using translation from Abū Dāʾūd 2226)
قَالَ رَسُولُ اللهِ ﷺ أَيُّمَا امْرَأَةٍ سَأَلَتْ زَوْجَهَا الطَّلَاقَ فِي غَيْرِ مَا بَأْسٍ فَحَرَامٌ عَلَيْهَا رَائِحَةُ الْجَنَّةِ
