He inspected the birds, and said: "What is the matter that I see not the hoopoe? Or is he among the absentees?
And he took attendance of the birds and said, "Why do I not see the hoopoe - or is he among the absent?
(27:20) (On another occasion) Solomon reviewed his birds *27 and said, "How is it that 1 do not see the hoopoe? Has he disappeared somewhere?
*27) That is, the birds whose troops, as mentioned above, were included in the armies of Prophet Solomon like the troops of the men and jinns. It is just possible that the Prophet Solomon had employed them for communicating messages, hunting and performing other such services.
