Selections from The Sayings and Preaching of Amir al-Muminin Ali ibn Abi Talib (Peace Be Upon Him) Including His Replies to Questions and Maxims Expressed for Various Purposes.
Translated by Sayyid Ali Reza

وَقَالَ (عليه ‏السلام):

Amir al-mu'minin, peace be upon him, said:

إِنَّ مَعَ كُلِّ إِنْسَانٍ مَلَكَيْنِ يَحْفَظَانِهِ،

With every individual there are two angels who protect him;

فَإِذَا جَاءَ الْقَدَرُ خَلَّيَا بَيْنَهُ وَبَيْنَهُ،

when destiny approaches they let it have its own way with him.

وَإِنَّ الاْجَلَ جُنَّةٌ حَصِينَةٌ.

Certainly, the appointed time is a protective shield (against the events which occur before it).
