'Allah is Sufficient for us and He Is the Best Disposer of affairs," was said by Abraham when he was thrown into the fire; and it was said by Muhammad when they (i.e. hypocrites) said, "A great army is gathering against you, therefore, fear them," but it only increased their faith and they said: "Allah is Sufficient for us, and He is the Best Disposer (of affairs, for us)." (3.173)  

{حَسْبُنَا اللَّهُ وَنِعْمَ الْوَكِيلُ} قَالَهَا إِبْرَاهِيمُ عَلَيْهِ السَّلاَمُ حِينَ أُلْقِيَ فِي النَّارِ وَقَالَهَا مُحَمَّدٌ ﷺ حِينَ قَالُوا {إِنَّ النَّاسَ قَدْ جَمَعُوا لَكُمْ فَاخْشَوْهُمْ فَزَادَهُمْ إِيمَانًا وَقَالُوا حَسْبُنَا اللَّهُ وَنِعْمَ الْوَكِيلُ}  

The last statement of Abraham when he was thrown into the fire was:--"Allah is Sufficient for us and He is the Best Disposer (of affairs for us)." (3.173) (Using translation from Bukhārī 4564)  

كَانَ آخِرُ كَلَامِ إِبْرَاهِيمَ حِينَ أُلْقِيَ فِي النَّارِ حَسْبِي اللَّهُ وَنِعْمَ الْوَكِيلُ وَقَالَ نَبِيُّكُمْ ﷺ مِثْلُهَا {الَّذِينَ قَالَ لَهُمُ النَّاسُ إِنَّ النَّاسَ قَدْ جَمَعُوا لَكُمْ فَاخْشَوْهُمْ فَزَادَهُمْ إِيمَانًا وَقَالُوا حَسْبُنَا} [آل عمران 173] اللَّهُ وَنِعْمَ الْوَكِيلُ  

[Machine] The last words of Prophet Ibrahim ﷺ when he was thrown into the fire were "Allah alone is sufficient for us, and He is the best disposer of affairs." And your Prophet Muhammad ﷺ said the same words to his people when they said to him, "Indeed, the people have gathered against you, so fear them." But that merely increased them in faith and they said, "Allah alone is sufficient for us, and He is the best disposer of affairs." [Surah Al-Imran 3:173]  

كَانَ آخِرَ كَلَامِ إِبْرَاهِيمَ عَلَيْهِ السَّلَامُ حِينَ أُلْقِيَ فِي النَّارِ حَسْبِيَ اللهُ وَنِعْمَ الْوَكِيلُ قَالَ وَقَالَ نَبِيُّكُمْ ﷺ مِثْلَهَا {الَّذِينَ قَالَ لَهُمُ النَّاسُ إِنَّ النَّاسَ قَدْ جَمَعُوا لَكُمْ فَاخْشَوْهُمْ فَزَادَهُمْ إِيمَانًا وَقَالُوا حَسْبُنَا} [آل عمران 173] اللهُ وَنِعْمَ الْوَكِيلُ
