Surah 45. Al-Jathiya, Ayah 4

Cf. 7:185 and the corresponding note [151]. - The intricate structure of human and animal bodies, and the life-preserving instincts with which all living creatures have been endowed, make it virtually impossible to assume that all this has developed "by accident"; and if we assume, as we must, that a creative purpose underlies this development, we must conclude, too, that it has been willed by a conscious Power which creates all natural phenomena "in accordance with an inner truth" (see note [11] on 10:5 ).

(2) These Signs are in our own nature and in the animals we meet with every day; here we have certainty within human limits: these are "for those of assured Faith".
