Sometimes the devil also speaks the truth. Yes!
Rasulullah Sallallahu alaihi wa Sallam described shaytaan when he (shaytaan) taught Hadhrat Abu Ayyoub Al-Ansaari Radhiyallahu anhu Aayatul Kursi as:
“صَدَقَتْ وَهِيَ كَذُوبٌ ”
‘Shaytaan told the truth and shaytaan is a continuous liar.’
Jami’ At-Tirmidhi 2880
Trump’s media outlet is called Truth Social but only lies emanates from his mouth. Shaytaan and liars are inseparable. Sometimes also liars speak the truth. Trump said with regards to vaccines:
