We know that our prophet, Mohammed (SAWS), had true dreams, yet there was a time for them to come true. And sometimes he did not know when they would come true. An example of this is during the sixth year of Hijrah, He (SAWS) had a dream that he and other Muslims were performing umrah in Makkah, safely and securely, with their hair cut or shaved ( an umrah requirement). He told this dream to his companions, and 1500 Muslims went with him that year to perform umrah. However, they were intercepted by the pagans in a suburb of Makkah called al-Hudaybiyah.
A great battle was about to ensue, but Allaah then instructed His Messenger (SAWS) to accept a truce with the pagans of Makkah. This truce would prevent the Muslims from performing umrah that year, but allow them to perform it the following year. This truce become know as the Hudaybiyah Truce.
Al-Miswar Bin Makramah, Sahl bin Hanif and other companions reported that, in the beginning, this truce angered many Muslims, who preferred to fight. “Umar was the most vocal about this, and he came to the Prophet (SAWS) objecting. “are you not truly Allah’s Prophet?” To which the Prophet (SAWS) replied “Yes, indeed.” ‘Umar said: “Why, then should we agree to this power position in regard to our religion?” The Prophet (SAWS) declared:
“Indeed, I am Allaah’s Messenger: I will not disobey Him, and He will surely give me victory”
Umar said, “But have you not told us that we will come to the House (al-Kabah) and perform tawaf around it?’ The Prophet (SAWS) replied, “Yes, indeed. But did I tell you we will do it this year?” Umar replied, “No.” The Prophet (SAWS) said, “Indeed, you will reach it and perform tawaf around it.”
Allaah then revealed: “Allaah has surely shown to His Messenger the dream in truth: You will surely enter the Sanctified Masjid (of Makkah)-if Allaah wills-securely, with your hair shaved or shortened, free from fear. He knew what you did not know and has arranged prior to that (dream) a near conquest.” (al-Fath:27)
So, as Allaah promised, the Muslims performed ‘umrah the next year, and they conquered Makkah one year thereafter.
