Nahj al-Balāgha

۳۷۷. وَقَالَ (عليه ‏السلام): لَا تَأْمَنَنَّ عَلَى خَيْرِ هذِهِ الْأُمَّةِ عَذَابَ اللهِ، لِقَوْلِهِ تَعَالى: ﴿فَلَا يَأْمَنُ مَكْرَ اللهِ إِلَّا الْقَوْمُ الْخَاسِرُونَ﴾

377. Amīr al-mu’minīn, peace be upon him said: Do not feel safe from the punishment of Allāh even about the best man in the whole community because Allāh, the Sublime, says: But no one feels secure against the plan of Allāh save the people (who are the) losers. (Qur’ān, 7:99).

وَلَا تَيْأَسَنَّ لِشَرِّ هَذِهِ الْأُمَّةِ مِنْ رَوْحِ اَللَّهِ لِقَوْلِهِ تَعَالَى: ﴿إِنَّهُ لَا يَيْأَسُ مِن رَّوْحِ اللهِ إِلَّا الْقَوْمُ الْكَافِرُونَ﴾.

Again, do not lose hope even for the worst man of the community because Allāh, the Sublime says : Verily, despairs not of Allāh’s mercy but the disbelieving people. (Qur’ān, 12:87).
