٤٧٣. وَقِيلَ لَهُ (عليه السلام) : لَوْ غَيَّرْتَ شَيْبَكَ يَا أَمِيرَ الْمُؤْمِنِينَ. فَقَالَ (عليه السلام) :
473. It was said to Amīr al-mu’minīn, peace be upon him: We wish you had changed your grey hair, O’ Amīr al-mu’minīn. Then he said:
Grief over the Prophet's death precludes adornment
Nahj al-Balāgha|Volume 1|Book 3|Chapter 473
الْخِضَابُ زِينَةٌ، وَنَحْنُ قَوْمٌ فِي مُصِيبَةٍ!
Dye is a way of adornment while we are in a state of grief.
قال السيد الرضي: يُرِيدُ وَفَاةَ رَسُولِ اللَّهِ (صلى الله عليه وآله).
as-Sayyid ar-Raḍī says: Amīr al-mu’minīn, peace be upon him, is referring to the death of the Messenger of Allāh, peace be upon him and his descendants.
