قَالَ الزُّهْرِيُّ: وَزَادَ بِلَالٌ فِي نِدَاءِ صَلَاةِ الْفَجْرِ: «الصَّلَاةُ خَيْرٌ مِنَ النَّوْمِ، فَأَقَرَّهَا نَبِيُّ اللَّهِ صلى الله عليه وسلم»، وَقَالَ عُمَرُ: «أَمَا إِنِّي قَدْ رَأَيْتُ مِثْلَ الَّذِي رَأَى، وَلَكِنَّهُ سَبَقَنِي»
Al-Zuhri (may Allah have mercy on him) said that Sayyiduna Bilal (may Allah be pleased with him) added these words to the adhan of the Fajr prayer: 'As-salatu khayrun min an-nawm' (Prayer is better than sleep), and the Prophet of Allah (peace and blessings be upon him) approved it. And Sayyiduna Umar (may Allah be pleased with him) said: "Indeed, I too had seen exactly the same dream as he saw, but he got ahead of me (in reporting it)."
