Hadith #11

11ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ إِسْمَاعِيلَ بْنِ رَبَاحٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ إِذَا صَلَّيْتَ وَأَنْتَ تَرَى أَنَّكَ فِي وَقْتٍ وَلَمْ يَدْخُلِ الْوَقْتُ فَدَخَلَ الْوَقْتُ وَأَنْتَ فِي الصَّلاَةِ فَقَدْ أَجْزَأَتْ عَنْكَ.

11. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from ibn abu ‘Umayr from ’Isma‘il ibn Rabah who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘If you perform Salah (prayer) and you think it is time, when in fact is not time yet, but the time comes when you are still performing that Salah (prayer) it is sufficient.’”
