وَقَالُوا۟ لَن تَمَسَّنَا ٱلنَّارُ إِلَّآ أَيَّامًۭا مَّعْدُودَةًۭ ۚ قُلْ أَتَّخَذْتُمْ عِندَ ٱللَّهِ عَهْدًۭا فَلَن يُخْلِفَ ٱللَّهُ عَهْدَهُۥٓ ۖ أَمْ تَقُولُونَ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ
And they say: The Fire (of punishment) will not touch us save for a certain number of days. Say: Have ye received a covenant from Allah - truly Allah will not break His covenant - or tell ye concerning Allah that which ye know not?

Interpretation of Dreams
Chapter: If one sees (in a dream) cows being slaughtered
Narrated Abu Musa:
The Prophet (ﷺ) said, "I saw in a dream that I was migrating from Mecca to a land where there were date palm trees. I thought that it might be the land of Al-Yamama or Hajar, but behold, it turned out to be Yathrib (i.e. Medina). And I saw cows (being slaughtered) there, but the reward given by Allah is better (than worldly benefits). Behold, those cows proved to symbolize the believers (who were killed) on the Day (of the battle) of Uhud, and the good (which I saw in the dream) was the good and the reward and the truth which Allah bestowed upon us after the Badr battle. (or the Battle of Uhud) and that was the victory bestowed by Allah in the Battle of Khaibar and the conquest of Mecca) .
