Do they not observe The birds above them, Spreading their wings and folding them in? None can uphold them Except (Allah) Most Gracious: Truly it is He That watches over all things.” Quran (67:19)
The Arabic word amsaka literally means, ‘to put one’s hand on, seize, hold, hold someone back,’ which expresses the idea that Allah holds the bird up in His power. These verses stress the extremely close dependence of the birds’ behaviour on Divine order. Modern scientific data has shown the degree of perfection attained by certain species of birds with regard to the programming of their movements. It is only the existence of a migratory programme in the genetic code of the birds that can explain the long and complicated journey that very young birds, without any prior experience and without any guide, are able to accomplish. They are also able to return to the departure point on a definite date.
Prof. Hamburger in his book ‘Power and Fragility’ gives the example of ‘mutton-bird’ that lives in the Pacific with its journey of over 15,000 miles in the shape of figure ‘8’. It makes this journey over a period of 6 months and comes back to its departure point with a maximum delay of one week. The highly complicated instructions for such a journey have to be contained in the birds’ nervous cells. They are definitely programmed. Should we not reflect on the identity of this ‘Programmer’?
