Yahya related to me from Malik from Ibn Shihab from al-Araj that Umar ibn al Khattab recited Surat an-Najm (Sura 53) and prostrated in it, and then got up and recited another sura.
أَنَّ عُمَرَ بْنَ الْخَطَّابِ قَرَأَ بِالنَّجْمِ إِذَا هَوَى فَسَجَدَ فِيهَا ثُمَّ قَامَ فَقَرَأَ بِسُورَةٍ أُخْرَى
[Machine] Ibn Al-Khattab read to them the passage: "By the star when it descends, your companion [Muhammad] has not strayed, nor has he erred, nor does he speak from [his own] inclination. It is not but a revelation revealed, taught to him by one intense in strength."
بْنَ الْخَطَّابِ ؓ قَرَأَ لَهُمْ وَالنَّجْمِ إِذَا هَوَى فَسَجَدَ فِيهَا ثُمَّ قَامَ فَقَرَأَ سُورَةً أُخْرَى
[Machine] Umar ibn Al-Khattab read to them [the verse] "By the star when it descends" [Surah An-Najm, verse 1] and he prostrated in it, then he stood up and recited another chapter.
أَنَّ عُمَرَ بْنَ الْخَطَّابِ ؓ قَرَأَ لَهُمْ {وَالنَّجْمِ إِذَا هَوَى} [النجم 1] فَسَجَدَ فِيهَا ثُمَّ قَامَ فَقَرَأَ سُورَةً أُخْرَى
"عَنْ أَبِى هُرَيْرَةَ أَنَّ عُمَرَ بْنَ الخَطَّابِ قَرَأَ بِهِمْ {وَالنَّجْمِ إِذَا هَوَى} سَجَدَ فيهَا، ثُمَّ قَامَ فَقَرأَ سُوَرة أخْرى".
