أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۖ قُلْ فَأْتُوا۟ بِسُورَةٍ مِّثْلِهِۦ وَٱدْعُوا۟ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ
Am yaqooloona iftar a hu qul fatoo bisooratin mithlihi wa o dAAoo mani ista t aAAtum min dooni All a hi in kuntum sa diqeen a And yet,61 they [who are bent on denying the truth] assert, "[Muhammad] has invented it!" Say [unto them]: "Produce, then, a surah of similar merit; and [to this end] call to your aid whomever you can, other than God, if what you say is true!"62
 - Mohammad Asad
Do they say: "He (the Prophet) has forged it?" Tell them: "If what you say be true; then produce one Surah like this, you may even call to your aid anyone you want other than Allah."
 - Muhammad Farooq-i-Azam Malik
Or do they claim, 'He1 made it up!'? Tell them 'O Prophet', 'Produce one sûrah like it then, and seek help from whoever you can- other than Allah- if what you say is true!'
 - Mustafa Khattab
Or say they: He hath invented it? Say: Then bring a surah like unto it, and call (for help) on all ye can besides Allah, if ye are truthful.
 - Marmaduke Pickthall
Or do they say "He forged it"? Say: "Bring then a Surah like unto it and call (to your aid) anyone you can besides Allah if it be ye speak the truth!" 1430
