Orphan In Islam

The people of jāhiliyyah read hundreds of verses of poetry of insults and slander
against the Prophet صلى الله عليه وسلم ,and although poetry was the media of the Arabs history
has not recorded a single verse of it, but it has recorded all of his sayings

Many ideologies, theories and beliefs are based upon assumption in the form of certainty, because the Nafs desires it, so it turns it into certainty :

(وَمَا یَتَّبِعُ أَكۡثَرُهُمۡ إِلَّا ظَنًّاۚ إِنَّ ٱلظَّنَّ لَا یُغۡنِی مِنَ ٱلۡحَقِّ شَیۡـًٔاۚ إِنَّ ٱللَّهَ عَلِیمُۢ بِمَا یَفۡعَلُونَ)
[Surah Yunus 36]

“And most of them follow not except assumption. Indeed, assumption avails not against the truth at all.”
[Surah Yūnus 10:36]
