Observing Prayer Early in the Period - Section 2
وَعَنْ مُعَاذِ بْنِ جَبَلٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " أَعْتِمُوا بِهَذِهِ الصَّلَاةِ فَإِنَّكُمْ قَدْ فُضِّلْتُمْ بِهَا عَلَى سَائِرِ الْأُمَمِ وَلَمْ تُصَلِّهَا أُمَّةٌ قَبْلَكُمْ. رَوَاهُ أَبُو دَاوُد
Mu'adh b, Jabal reported God’s Messenger as saying, “Observe this prayer when it is dark, for by it you have been made superior to all the peoples, no people having observed it before you”. Abu Dawud transmitted it.
