Speech of opposition : Hujur Pak Sallallahu Alaihi Wasallam do not know about the unseen knowledge. Believing that Hujur Pak Sallallahu Alaihi Wasallam knew the unseen is sick.
What is said in Islam : It is ‘Kufri to believe that Hujur Pak Sallallahu Alaihi Wasallam did not knew ‘Gaib. Allah is ‘Aalimul Gaaib (knows everything) and Hujur Pak Sallallahu Alaihi Wasallam is ‘Muttala Aalaal Gaib (knows everything by the power of Allah). Because it is said in Hadish ,”Allah gave all kind of knowledge to his Rasool Hujur Pak Sallallahu Alaihi Wasallam.
