The Messenger of Allah ﷺ did not make a prostration at any verse in al-Mufassal from the time he moved to Medina.  

أَنَّ رَسُولَ اللَّهِ ﷺ لَمْ يَسْجُدْ فِي شَىْءٍ مِنَ الْمُفَصَّلِ مُنْذُ تَحَوَّلَ إِلَى الْمَدِينَةِ  

"I recited to the Messenger of Allah ﷺ (Surat) An-Najm and he did not prostrate in it."  

قَرَأْتُ عَلَى رَسُولِ اللَّهِ ﷺ النَّجْمَ فَلَمْ يَسْجُدْ فِيهَا  

Zaid was imam (in a prayer) and he did not make prostration.  

عَنِ النَّبِيِّ ﷺ بِمَعْنَاهُ
