Mishkat al-Masabih, 1352

Al-Bara’ said, "I accompanied God’s Messenger on eighteen journeys and I never saw him fail to pray two <i>rak'as</i> when the sun had passed the meridian before praying the noon prayer.” Abu Dawud and Tirmidhi transmitted it, Tirmidhi saying that this is a <i>gharib</i> tradition.

وَعَن الْبَراء قَالَ: صَحِبْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ثَمَانِيَةَ عَشَرَ سَفَرًا فَمَا رَأَيْتُهُ تَرَكَ رَكْعَتَيْنِ إِذَا زَاغَتِ الشَّمْسُ قَبْلَ الظُّهْرِ. رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيبٌ
