حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ شُعْبَةَ، عَنْ عَبْدِ رَبِّهِ بْنِ سَعِيدٍ، عَنْ مُحَمَّدِ بْنِ يَحْيَى بْنِ حَبَّانَ، عَنِ ابْنِ مُحَيْرِيزٍ، عَنِ الْمُخْدِجِيِّ، عَنْ عُبَادَةَ بْنِ الصَّامِتِ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ ‏"‏ خَمْسُ صَلَوَاتٍ افْتَرَضَهُنَّ اللَّهُ عَلَى عِبَادِهِ فَمَنْ جَاءَ بِهِنَّ لَمْ يَنْتَقِصْ مِنْهُنَّ شَيْئًا اسْتِخْفَافًا بِحَقِّهِنَّ فَإِنَّ اللَّهَ جَاعِلٌ لَهُ يَوْمَ الْقِيَامَةِ عَهْدًا أَنْ يُدْخِلَهُ الْجَنَّةَ وَمَنْ جَاءَ بِهِنَّ قَدِ انْتَقَصَ مِنْهُنَّ شَيْئًا اسْتِخْفَافًا بِحَقِّهِنَّ لَمْ يَكُنْ لَهُ عِنْدَ اللَّهِ عَهْدٌ إِنْ شَاءَ عَذَّبَهُ وَإِنْ شَاءَ غَفَرَ لَهُ ‏"‏ ‏.‏

But whoever does thembutomits something from them out of negligence, will not have such acovenant with Allah; if He wills He will punish him, and if He wills,He will forgive him.’” Translation Not Available
