أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۚ بَلْ هُوَ ٱلْحَقُّ مِن رَّبِّكَ لِتُنذِرَ قَوْمًا مَّآ أَتَىٰهُم مِّن نَّذِيرٍ مِّن قَبْلِكَ لَعَلَّهُمْ يَهْتَدُونَ
Am yaqooloonaf taraahu bal huwal haqqu mir rabbika litunzira qawma maaa ataahum min nazeerim min qablika la'allahum yahtadoon
Yet they say, ‘Muhammad has made it up.’ No indeed! It is the Truth from your Lord for you [Prophet], to warn a people who have had no one to warn them before, so that they may be guided.
Or do they say, "He has invented it"? No — it is the truth from your Lord, so you may warn a people to whom no warner came before you, that they might be guided.
