He warned the disbelievers they would inevitably be defeated
it is possible to see the prophet (saas)'s trust in and submission and devotion to allah in his every word and deed. even in the most difficult of times, the prophet (saas) was certain that allah would help him, that the faithful would be victorious and that the disbelievers would be disappointed.
say to those who disbelieve: "you will be overwhelmed and crowded into hell. what an evil resting-place!" (surah al 'imran: 12)
the prophet (saas) stated the following in one of the hadiths:
"whatever you have been promised will surely come to pass, and you cannot escape (it)."61
