Nahj al-Balāgha

ومن كلام له (عليه السلام) لمّا خُوِّف من الغيلة

When Amīr al-mu’minīn was warned of being killed by deceit, he said:

وَإِنَّ عَلَيَّ مِنَ اللهِ جُنَّةً حَصِينةً، فَإِذَا جَاءَ يَوْمِي انْفَرَجَتْ عَنِّي وَأَسْلَمَتْنِي؛ فَحِينَئِذٍ لاَ يَطِيشُ السَّهْمُ وَلاَ يَبْرَأُ الْكَلْمُ.

Surely, there is a strong shield of Allāh over me. When my day would come it would get away from me and hand me over to death. At that time neither an arrow would go amiss nor a wound would heal up.
