Concise Quran Commentary
Perhaps you, O Messenger, because of their disbelief, stubbornness and demand for signs, will leave out conveying some of what Allah has instructed you to convey because they will find it difficult to practise; and perhaps your heart will be reluctant to convey it, so that they do not say, ‘Why has no rich treasure been sent down to him or why has no angel come with him to confirm his truthfulness?’ Do not leave some of what is revealed to you because of that. You are only a warner who conveys what Allah has instructed you to convey. You do not have to bring the signs they request for. Allah takes care of everything.
