Allah the Almighty said: "So remain on a right course as you have been commanded" [Hud 112],

and He also said: "Indeed, those who have said, 'Our Lord is Allah' and then remained steadfast - the angels will descend upon them, [saying], 'Do not fear and do not grieve but receive good tidings of Paradise, which you were promised. We are your allies in this worldly life and in the Hereafter. And you will have therein whatever your souls desire, and you will have therein whatever you request, as accommodation from a [Lord who is] Forgiving and Merciful.'" [Fussilat 30-32],

and He said: "Indeed, those who have said, 'Our Lord is Allah' and then remained steadfast - there will be no fear concerning them, nor will they grieve. Those are the companions of Paradise, abiding eternally therein as a reward for what they used to do." [Ahqaf 13-14].

قَالَ الله تَعَالَى: ﴿فَاسْتَقِمْ كَمَا أُمِرْتَ﴾ [هود: ١١٢]،

وَقالَ تَعَالَى: ﴿إِنَّ الَّذِينَ قَالُوا رَبُّنَا اللَّهُ ثُمَّ اسْتَقَامُوا تَتَنَزَّلُ عَلَيْهِمُ الْمَلائِكَةُ أَلاَّ تَخَافُوا وَلا تَحْزَنُوا وَأَبْشِرُوا بِالْجَنَّةِ الَّتِي كُنْتُمْ تُوعَدُونَ نَحْنُ أَوْلِيَاؤُكُمْ فِي الْحَيَاةِ الدُّنْيَا وَفِي الآخِرَةِ وَلَكُمْ فِيهَا مَا تَشْتَهِي أَنْفُسُكُمْ وَلَكُمْ فِيهَا مَا تَدَّعُونَ نُزُلًا مِنْ غَفُورٍ رَحِيمٍ﴾ [فصلت: ٣٠ - ٣٢]،

وَقالَ تَعَالَى: ﴿إِنَّ الَّذِينَ قَالُوا رَبُّنَا اللهُ ثُمَّ اسْتَقَامُوا فَلا خَوْفٌ عَلَيْهِمْ وَلا هُمْ يَحْزَنُونَ أُولَئِكَ أَصْحَابُ الْجَنَّةِ خَالِدِينَ فِيهَا جَزَاءً بِمَا كَانُوا يَعْمَلُونَ﴾ [الأحقاف: ١٣ - ١٤].
