Verse [ 105:3] طَيْرًا أَبَابِيلَ (... birds in flocks.) The word ababil is plural and is said to have no singular. It means birds in flocks, or swarms of birds. It is not the name of a particular bird. In Urdu usually ababil refers to 'swallows', they are not implied in the verse as indicated in the above narration. These birds were somewhat smaller in size than pigeon and they were birds that were never seen before. [ Said Ibn Jubair, as quoted by Qurtubi ].
