Observing and reflecting: these verses call for both, inviting people to travel through the earth and consider the end of the disbelievers and the corrupters. They turn the gaze to the realm of the heavens and the earth, to the rain that revives the land, to the blessings of night and day and to ships sailing on the sea, and they also invite reflection on the Quran.
Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
Say, "Have you considered your 'partners' whom you invoke besides Allāh? Show me what they have created from the earth, or have they partnership [with Him] in the heavens? Or have We given them a book so they are [standing] on evidence therefrom? [No], rather, the wrongdoers do not promise each other except delusion."
And if you asked them, "Who created the heavens and the earth?" they would surely say, "Allāh." Say, "Then have you considered what you invoke besides Allāh? If Allāh intended me harm, are they removers of His harm; or if He intended me mercy, are they withholders of His mercy?" Say, "Sufficient for me is Allāh; upon Him [alone] rely the [wise] reliers."
