Sunan an-Nasa'i
It was narrated that 'Irak bin Malik said: "I heard Nawfal bin Mu'awiyah say: 'There is a prayer which if a person misses it, it is as of he has been robbed of his family and his wealth.'" Ibn 'Umar said: "The Messenger of Allah (ﷺ) said: 'It is 'Asr prayer.'"
أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعْدِ بْنِ إِبْرَاهِيمَ بْنِ سَعْدٍ، قَالَ حَدَّثَنِي عَمِّي، قَالَ حَدَّثَنَا أَبِي، عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ، قَالَ حَدَّثَنِي يَزِيدُ بْنُ أَبِي حَبِيبٍ، عَنْ عِرَاكِ بْنِ مَالِكٍ، قَالَ سَمِعْتُ نَوْفَلَ بْنَ مُعَاوِيَةَ، يَقُولُ صَلاَةٌ مَنْ فَاتَتْهُ فَكَأَنَّمَا وُتِرَ أَهْلَهُ وَمَالَهُ . قَالَ ابْنُ عُمَرَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " هِيَ صَلاَةُ الْعَصْرِ " .
