Yahya related to me from Malik from Rabia ibn Abi Abd ar-Rahman that al Qasim ibn Muhammad said, "None of the companions that I met prayed dhuhr until well after noon,"(i.e.until when the sun had lost its fierceness).
أَنَّهُ قَالَ مَا أَدْرَكْتُ النَّاسَ إِلاَّ وَهُمْ يُصَلُّونَ الظُّهْرَ بِعَشِيٍّ
