Here the two Rafidi clowns, the Park Runner and his brother the Tweezer using the same folklore belief (biLaL strUgGLed wiTh aRaBic/pRonuNciaTioN) and my response:
"The 'sin' (س) of Bilal is 'shin' (ش) in the hearing of God."
1. The narration (him struggling with basic Arabic letters!) is a fabrication, the scholars say it has no basis at all...
Bilal the Habashi was a master of Arabic eloquency, a native Makkan, (miss)using him as a token for championing blackness in Islam or worse, justifying ones/others failure (like learning basics such as Tajwid) is nothing but an insult to him.
