قَالَ يَحْيَى: قَالَ مَالِك: لَمْ تَزَلِ الصُّبْحُ يُنَادَى لَهَا قَبْلَ الْفَجْرِ فَأَمَّا غَيْرُهَا مِنَ الصَّلَوَاتِ فَإِنَّا لَمْ نَرَهَا يُنَادَى لَهَا إِلَّا بَعْدَ أَنْ يَحِلَّ وَقْتُهَا
Imam Malik, may Allah have mercy on him, said that the adhan for the morning prayer has always been given before its time since ancient times, but the adhan for the other prayers should be after their time has begun.
