Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 31
وَ دَخَلَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ اَلْمَسْجِدَ وَ فِيهِ نَاسٌ مِنْ أَصْحَابِهِ فَقَالَ «تَدْرُونَ مَا قَالَ رَبُّكُمْ» قَالُوا اَللَّهُ وَ رَسُولُهُ أَعْلَمُ قَالَ «إِنَّ رَبَّكُمْ يَقُولُ إِنَّ هَذِهِ اَلصَّلَوَاتِ اَلْخَمْسَ اَلْمَفْرُوضَاتِ مَنْ صَلاَّهُنَّ لِوَقْتِهِنَّ وَ حَافَظَ عَلَيْهِنَّ لَقِيَنِي يَوْمَ اَلْقِيَامَةِ وَ لَهُ عِنْدِي عَهْدٌ أُدْخِلُهُ بِهِ اَلْجَنَّةَ، وَ مَنْ لَمْ يُصَلِّهِنَّ لِوَقْتِهِنَّ وَ لَمْ يُحَافِظْ عَلَيْهِنَّ فَذَاكَ إِلَيَّ إِنْ شِئْتُ عَذَّبْتُهُ وَ إِنْ شِئْتُ غَفَرْتُ لَهُ.
"The Messenger of Allah صلى الله عليه وعلى آله وسلم entered the mosque where some of his companions were present and said: "Do you know what your Lord عز وجل has said?" They replied: "Allah سبحانه وتعالى and His Messenger know best." He صلى الله عليه وعلى آله وسلم said: "Your Lord عز وجل says: 'These five obligatory prayers—whoever performs them at their appointed times and maintains them, will meet Me on the Day of Judgment with a promise from Me to admit him into Paradise. And whoever does not perform them at their appointed times and does not maintain them, then that is up to Me—if I wish, I will punish him, and if I wish, I will forgive him.'"
