Or do they say, "In him is madness?" Rather, he brought them (23:70)

Almuntakhab Fi Tafsir Alquran Alkarim

Or do they accuse him of being possessed, ruinously imprudent or insane! Indeed, he is a person steadfast in adherence to His Creator and His cause and he brought them -these Pagans- the very truth guiding into all truth, but how hateful to most of them is the truth

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(23:70) Or, are they really convinced that he is possessed (by a jinn)? *67 Nay! the real thing is that he has brought the Truth and most of them have aversion to the Truth.

Or do they say, "In him is madness?" Rather, he brought them meaning

*67) That is, "Do they reject his Message because they regard Muhammad (Allah's peace be upon him) to be possessed by a jinn? No, this is also not correct, because in their heart of hearts, they themselves regard him as a wise and sagacious person. It is therefore ridiculous to regard a man like him to be possessed by a jinn, for such a person cannot say wise things and do noble deeds like him. How strange that a person possessed by a jinn (or having epileptic fits according to the western orientalists) should utter and recite sublime discourses of the Qur'an and start and guide a successful Movement which should revolutionise the way of life not only of his own people but of the whole world."

یا یہ اس بات کے قائل ہیں کہ وہ مجنون ہے؟ نہیں، بلکہ وہ حق لایا ہے اور حق ہی ان کی اکثریت کو ناگوار ہے
