‘Ubadah ibn al-Samit reported: The Messenger of Allah, peace and blessings be upon him, said, “The Angel Gabriel, upon him be peace, came to me from my Lord and he said, ‘O Muhammad, Allah Almighty says: Verily, I have obligated five prayers upon your nation. Whoever fulfils them with their ablution, their timings, their bowings, and their prostrations, then he has a promise from Me that he will enter Paradise. But whoever meets Me with any shortcomings in them, he does not have a promise from Me. If I wish, I will punish him, and if I wish, I will have mercy upon him.”

عَنْ عُبَادَة بْن الصَّامِتِ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَتَانِي جِبْرِيلُ عَلَيْهِ السَّلَامُ مِنْ عِنْدِ اللهِ فَقَالَ يَا مُحَمَّدُ إِنَّ اللهَ تَعَالَى يَقُولُ إِنِّي قَدْ فَرَضْتُ عَلَى أُمَّتِكَ خَمْسَ صَلَوَاتٍ مَنْ وَفَى بِهِنَّ عَلَى وُضُوئِهِنَّ وَمَوَاقِيتِهِنَّ وَرُكُوعِهِنَّ وَسُجُودِهِنَّ فَإِنَّ لَهُ عِنْدِي بِهِنَّ عَهْدًا أَنْ أُدْخِلَهُ الْجَنَّةَ وَمَنْ لَقِينِي وَقَدِ انْتَقَصَ مِنْ ذَلِكَ شَيْئًا فَلَيْسَ لَهُ عِنْدِي عَهْدٌ إِنْ شِئْتُ عَذَّبْتُهُ وَإِنْ شِئْتُ رَحِمْتُهُ
