The Prophet ﷺ said: If anyone keeps on praying regularly four rak'ahs before and four after the noon prayer, he will not enter the Hell-fire. Abu Dawud said: Al-'Ala' bin Al-Harith and Sulaiman bin Musa reported it from Makhul with his chain, similarly. (Using translation from Abū Dāʾūd 1269)
قَالَ رَسُولُ اللهِ ﷺ «مَنْ حَافَظَ عَلَى أَرْبَعِ رَكَعَاتٍ قَبْلَ الظُّهْرِ وَأَرْبَعٍ بَعْدَهَا حَرَّمَهُ اللهُ عَلَى النَّارِ»
