To his brother Aqil
Nahj al-Balāgha|Volume 1|Book 2|Chapter 36
فَإِنْ تَسْأَلِينِي كَيْفَ أَنْتَ فَإِنَّنِي * صَبُورٌ عَلَى رَيْبِ الزَّمَانِ صَلِيبُ يَعِزُّ عَلَيَّ أَنْ تُرَى بِي كَآبَةٌ * فَيَشْمَتَ عَادٍ أَوْ يُسَاءَ حَبِيبُ
If you enquire how I am, then listen that I am enduring and strong against the vicissitudes of time. I do not allow myself to be grieved lest the foe feels joyful and the friend feels sorry.
