Hadith

قالَ الإمام علي عَلَيْهِ اَلسَّلاَمُ: عَلَى قَبْرِ رَسُولِ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ سَاعَةَ دَفْنِهِ: إِنَّ اَلصَّبْرَ لَجَمِيلٌ إِلاَّ عَنْكَ وَ إِنَّ اَلْجَزَعَ لَقَبِيحٌ إِلاَّ عَلَيْكَ وَ إِنَّ اَلْمُصَــابَ بِكَ لَجَلِيلٌ وَ إِنَّهُ قَبْلَكَ وَ بَعْدَكَ لَجَلَلٌ 

Amir al-mu’minin, peace be upon him, said on the grave of the Messenger of Allah, peace be upon him and his escendants, at the time of burial: Certainly, endurance is good except about you; fretting is bad except over you; and the affliction about you is great while every other affliction before or after it is small.

Nahj al-Balagha, Saying 292
