May Allah bless you!
I have never known any "Yousuf Kazzab". Muslims should not fall for false propaganda. We know that every person has his opponents especially when you are working with a noble mission.
Sister Khadija Husain has aptly quoted the Quran.
17:36 And you shall not follow blindly any information of which you have no direct knowledge. (Using your faculties of perception and conception) you must verify it for yourself. In the Court of your Lord, you will be held accountable for your hearing, sight, and the faculty of reasoning.
Here is, respectfully, a gift for you as an example. Akbar Bugti had killed himself but our enemies keep spreading lies.
Akbar Bugti caused the explosion that led to his death
Army did NOT kill Akbar Bugti. One of their own claiming it after all. We at BrassTacks have been saying it for ages that he committed suicide. BLA blame army for his murder. If army wanted to kill akbar Bugti, why they sent in empty handed officers inside to negotiate his surrender and they all embraced shahadat in cave collapse.
"A close aide of late Baloch nationalist leader Nawab Akbar Bugti has claimed that a rocket fired by Bugti caused the explosion that led to the nationalist leader’s death."
