كتاب وقوت الصلاة

The Times of Prayer

Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, said, "If someone misses the asr prayer it is as if he has suffered a great misfortune in his family and wealth ."

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ الَّذِي تَفُوتُهُ صَلاَةُ الْعَصْرِ كَأَنَّمَا وُتِرَ أَهْلَهُ وَمَالَهُ ‏"‏ ‏.‏
