An interesting observation about surat Alqamar (54) is that it has 55 ayas all ending with the letter r. The number 55 is the order of Surat ArRahman and r is the first letter of Rahman. It could be that all this is to stress the significance of Surat ArRahman. Additionally, the last verse of Surat Alqamar connects well with the first verse of Surat ArRahman. 054:55 in the abode of truthfulness with an omnipotent King. 055:1 ArRahman.
