What is disinformation in it ?
1 - That Zaid Hamid was a Khalifa of Yousuf Kazzab ?
2- That Yousuf Kazzab claimed to be prophet ?
Yousuf Kazzab was convicted by a court of law after a lengthy trial. Zaid Hamid, Yousuf's Khalifa, appeared in court to defend his Prophet. Both of these are facts and are a part of the court record. At the time, Zaid Zaman Hamid used to go by the name of ZAID ZAMAN. After Yusuf's death, Zaid ZAMAN went into hiding and resurfaced in 2007 and started using the name Zaid HAMID. For your information provided below is a link to the Court Judgement on the Yousuf Kazzab case. You will find references to ZAID ZAMAN aka ZAID HAMID in the court judgement. Just search for Zaid Zaman.
