Narrated Usama bin Zaid:
Once the Prophet (ﷺ) stood over one of the high buildings of Medina and then said (to the people), “Do you see what I see?” They said, “No.” He said, “I see afflictions falling among your houses as rain drops fall.” [Sahih Bukhari]
The Hadith shows that the Prophet (PBUH) was given knowledge about some of the signs of the Hour. Today we can see the truthfulness of this Hadith in which it is mentioned that afflictions will affect us like rain drops. Everywhere you look you see Muslims in every country being killed and oppressed.
