مُحَمَّدُ بْنُ عَلِيِّ بْنِ مَحْبُوبٍ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنِ اِبْنِ أَبِي عُمَيْرٍ عَنْ إِسْمَاعِيلَ بْنِ رَبَاحٍ[ رَبَاحٍ خ ل] عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« إِذَا صَلَّيْتَ وَ أَنْتَ تَرَى أَنَّكَ فِي وَقْتٍ وَ لَمْ يَدْخُلِ اَلْوَقْتُ فَدَخَلَ اَلْوَقْتُ وَ أَنْتَ فِي اَلصَّلاَةِ فَقَدْ أَجْزَأَتْ عَنْكَ»
Narrated Muhammad ibn Ali ibn Mahbub from Ya’qub ibn Yazid from Ibn Abi ‘Umayr from Isma’il ibn Rabah:
Abu Abdillah عليه السلام said: "If you pray while thinking that you are within the time (of the prayer), and the time has not yet actually begun, and then the time enters while you are in the prayer, then it suffices for you."
