If Only …
Bismillah
Allah (سبحانه وتعالى) says in Suratul Anbiya:
لَوْ يَعْلَمُ الَّذِينَ كَفَرُوا حِينَ لَا يَكُفُّونَ عَن وُجُوهِهِمُ النَّارَ وَلَا عَن ظُهُورِهِمْ وَلَا هُمْ يُنصَرُونَ Translation: If only those who disbelieved knew when they will not be able to ward off the Fire from their faces, nor from their backs; and they will not be helped. [Surah Suratul Anbiya, verse 39]
The word for ward off is “yakuffoona”, “يَكُفُّونَ” and this is from the root word “ka-fa-fa” or “kaff” which means palm/hand.
