(V.3:28) The Statement of Allâh عز وجل "But Allâh warns you against Himself (i.e. His Punishment)." (3:28).
Narrated ‘Abdullâh رضي الله عنه: The Prophet صلى الله عليه وسلم said, "There is none who has a greater sense of Ghairah * than Allâh, and for that reason He has forbidden Al-Fawâhish , (the shameful deeds and sins, e.g. illegal sexual intercourse). And there is none who likes to be praised more than Allâh does." (Sahih Al-Bukhâri, Vol.9, Hadîth No.500).
* Ghairah: a feeling of great fury and anger when one’s honour and prestige are injured or challenged.
