In a well-known illustration, Thābit ibn Mūsā al-Zāhid heard a phrase connecting frequent night prayer with a radiant appearance by day in the setting of a teacher's transmission. Some versions came to be presented as a prophetic narration even though such attribution was not established.
«مَنْ كَثُرَتْ صَلَاتُهُ بِاللَّيْلِ حَسُنَ وَجْهُهُ بِالنَّهَارِ»
Whoever prays much at night will have a pleasing face during the day.
The wording is not being cited as an authenticated Prophetic hadith. It illustrates how a contextual statement can be misheard as part of an isnād transmission. Attractive moral meaning is never sufficient proof of prophetic attribution.
