Mauquf Sahih Graded by Salim al-Hilali Book of The Times of Prayer · Hadith 12 of 1,858وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ رَبِيعَةَ بْنِ أَبِي عَبْدِ الرَّحْمَنِ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، أَنَّهُ قَالَ مَا أَدْرَكْتُ النَّاسَ إِلاَّ وَهُمْ يُصَلُّونَ الظُّهْرَ بِعَشِيٍّ .
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)
