Surely, there is a lesson in their history for those who are endowed with intelligence; this Speech is not being forged, but It is testifying what was before It and a detailed explanation of everything and Guidance and Mercy for the believing people.
Hadeeth (Speech) is one among the 40 names of Adhikr as mentioned in 12 places such as in 7: 185; 18: 2; 39: 23 and 53: 59. Adhikr which explains each and everything is a Guidance, Mercy, and Herald for those who submit everything to Lord Allah as explained in verse 16: 89. Adhikr-the Splendid Book-is testifying and safeguarding all the previous 312 Books as explained in verse 5: 48. But Adhikr will increase filth over filth for the hypocrites and Mushriks as explained in verse 9: 125. See explanation 6: 38, 153 and 7: 52.
