Hadith 4297
وَفِي رِوَايَةٍ لَهُ: قَالَ: «لَا تُرْسِلُوا فَوَاشِيكُمْ وَصِبْيَانَكُمْ إِذَا غَابَتِ الشَّمْسُ حَتَّى تَذْهَبَ فَحْمَةُ الْعِشَاءِ فَإِنَّ الشَّيْطَانَ يَبْعَثُ إِذَا غَابَتِ الشَّمْسُ حَتَّى تذْهب فَحْمَة الْعشَاء»
In a version by him he said, “Do not let your animals and children go at large when the sun sets till the first and darkest part of the night has passed, for the devil is sent out; from the time the sun sets till the first and darkest part of the night is past.”
