The whole knowledge of The Unseen (Al-Ghaib) is with Allah (SWT) (Say: None in the heavens and the earth knows The (whole) Ghalib ( The Unseen) except Allah). (Sura 27, verse 65) and He grants whatever He wants to whomever He wants from His humble servants some part of that knowledge. Some prophets get more than other prophets depending the degree of knowledge, dedication and humbleness. The greatest degree is for the Best Prophet Muhammad (SAWA) and his Holy Progeny Ahlul Bayt (AS). Allah (SWT) granted some prophets more degree than other prophets (We have granted some prophets more degrees than other prophets) (Sura 17, verse 55). The gift of the knowledge of unseen from Allah (SWT) will vary between prophet to another prophet.
