سورة المزمل

Ali ibn Ibrahim (may Allah have mercy on him): فَکَیْفَ تَتَّقُونَ إِنْ کَفَرْتُمْ یَوْماً یَجْعَلُ الْوِلْدانَ شِیباً [How, then, will you guard yourselves, if you disbelieve, on the day which shall make children grey-headed] — when the children hear that cry and shout, they become old out of fear.

Imam Ali (peace be upon him): Fear the day on which deeds are examined and reckoned. A day full of turmoil and distress, in which children become old.

The Prophet (peace be upon him and his family): Allah the Mighty and Majestic commands a fire whose name is al-Falaq and which has the most severe punishment of Hell, and that fire comes out from its place — which is a black, dark place full of shackles and chains. Allah the Mighty and Majestic commands that fire to blow once on the faces of the creatures, so it blows; and from the intensity and terror of its blowing on the Day of Resurrection, the sky is split open, the stars are effaced, the seas dry up, the mountains crumble, eyes are blinded, pregnant mothers miscarry their children, and children become old.
