Mahdi Activities Pre-Qiyamah – OpEd
"They ask you (O Muhammad) about the Hour (Qiyahmah) when will be its appointed time? You have no knowledge to say anything about it. To your Lord belongs (knowledge of) the term. You (O Muhammad) are only a warner for those who fear." (Qur'an 79:42-45)
According to Islamic tradition, the Day of Judgment (Qiyahmah) is a very just event where every human soul accounts for all of their actions. While some Muslim scholars have suggested a 1500-year period, scholarly consensus emphasizes that only Allah knows the exact time.
