مُحَمَّدُ بْنُ عَلِيِّ بْنِ مَحْبُوبٍ عَنْ أَحْمَدَ بْنِ اَلْحَسَنِ بْنِ عَلِيِّ بْنِ فَضَّالٍ عَنْ عَلِيِّ بْنِ يَعْقُوبَ اَلْهَاشِمِيِّ عَنْ مَرْوَانَ بْنِ مُسْلِمٍ عَنْ عُبَيْدِ بْنِ زُرَارَةَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« لاَ يَفُوتُ اَلصَّلاَةُ مَنْ أَرَادَ اَلصَّلاَةَ لاَ يَفُوتُ صَلاَةُ اَلنَّهَارِ حَتَّى تَغِيبَ اَلشَّمْسُ وَ لاَ صَلاَةُ اَللَّيْلِ حَتَّى يَطْلُعَ اَلْفَجْرُ وَ لاَ صَلاَةُ اَلْفَجْرِ حَتَّى تَطْلُعَ اَلشَّمْسُ»
Muhammad ibn Ali ibn Mahbub narrated from Ahmad ibn Al-Hasan ibn Ali ibn Faddal from Ali ibn Ya'qub Al-Hashimi from Marwan ibn Muslim from Ubayd ibn Zurarah:
Abu Abdillah عليه السلام, peace be upon him, said: "The prayer is not missed by one who intends to pray. The prayer of the day is not missed until the sun sets, and the prayer of the night is not missed until the dawn rises, and the prayer of Fajr is not missed until the sun rises."
