The First Surah in which a Prostration is revealed
Al-Bukhari recorded that `Abdullah (bin Mas`ud) said, "Surat An-Najm was the first Surah in which a prostration was revealed. The Prophet (recited it in Makkah) and prostrated. Those who were with him did the same, except an old man who took a handful of soil and prostrated on it. Later on, I saw him killed as a disbeliever; he was Umayyah bin Khalaf.'' Al-Bukhari recorded this Hadith in several places of his Sahih, as did Muslim, Abu Dawud and An-Nasa'i, using various chains of narration through Abu Ishaq from `Abdullah.
﴿ بِسۡمِ ٱللَّهِ ٱلرَّحۡمَـٰنِ ٱلرَّحِيمِ ﴾
In the Name of Allah, the Most Gracious, the Most Merciful.
﴿ وَٱلنَّجۡمِ إِذَا هَوَىٰ • مَا ضَلَّ صَاحِبُكُمۡ وَمَا غَوَىٰ • وَمَا يَنطِقُ عَنِ ٱلۡهَوَىٰٓ • إِنۡ هُوَ إِلَّا وَحۡىٌ۬ يُوحَىٰ ﴾
(1. By the star when it goes down.) (2. Your companion has neither gone astray nor has he erred.) (3. Nor does he speak of desire.) (4. It is only a revelation revealed.)
