Muwatta Malik, Book 11, Hadith 4 (USC-MSA) ⓘ

Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyab said, "The Messenger of Allah, may Allah bless him and grant him peace, did not pray dhuhr and asr on the day of the Trench until after the sun had set." Malik said, "The hadith of al- Qasim ibn Muhammad from Salih ibn Khawwat is the one I like most out of what I have heard about the fear prayer."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّهُ قَالَ مَا صَلَّى رَسُولُ اللَّهِ صلى الله عليه وسلم الظُّهْرَ وَالْعَصْرَ يَوْمَ الْخَنْدَقِ حَتَّى غَابَتِ الشَّمْسُ ‏.‏ قَالَ مَالِكٌ وَحَدِيثُ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنْ صَالِحِ بْنِ خَوَّاتٍ أَحَبُّ مَا سَمِعْتُ إِلَىَّ فِي صَلاَةِ الْخَوْفِ ‏.‏
