هَلْ يَنظُرُونَ إِلَّا السَّاعَةَ أَن تَأْتِيَهُم بَغْتَةً وَهُمْ لَا يَشْعُرُونَ
“Are they waiting (for anything) but the hour which will come upon them suddenly while they perceive not?”
Zorara bin Ayun said, I asked Imam Baqir (as) about the verse, “Are they waiting (for anything) but the hour which will come upon them suddenly?”
Imam (as) replied, It is ‘”he hour” of the rising of the Qaem (as) which “will come upon them suddenly.” (Taweel Al Ayat Al Zahirah page 552)
