(52) بَابُ إِبَاحَةِ الْأَذَانِ لِلصُّبْحِ قَبْلَ طُلُوعِ الْفَجْرِChapter 52: Permissibility of calling the Fajr adhan before dawn
Hadith Q401
إِذَا كَانَ لِلْمَسْجِدِ مُؤَذِّنَانِ لَا مُؤَذِّنٌ وَاحِدٌ، فَيُؤَذِّنُ أَحَدُهُمَا قَبْلَ طُلُوعِ الْفَجْرِ، وَالْآخَرُ بَعْدَ طُلُوعِهِ بِذِكْرِ خَبَرٍ مُجْمَلٍ غَيْرِ مُفَسَّرٍ.
When there are two muezzins in the mosque instead of one, and one of them gives the call to prayer before the break of dawn and the other gives the call to prayer after the break of dawn, in this regard, the mentioned narration is concise and unexplained.
