al-Sharif al-Radi (d. 406 AH) · Thaqalayn library edition, reproduced verbatim
لَقَدْ عَلِمْتُمْ أَنَّي أَحَقُّ بِهَا مِنْ غَيْرِي، وَوَاللهِ لاَسْلِمَنَّ مَاسَلِمَتْ أُمُورُ الْمُسْلِمِينَ، وَلَمْ يَكُنْ فِيهِا جَوْرٌ إِلاَّ عَلَيَّ خَاصَّةً، الْتمَاساً لاِجْرِ ذلِكَ وَفَضْلِهِ، وَزُهْداً فِيَما تَنافَسْتُمُوهُ مِنْ زُخْرُفِهِ وَزِبْرِجِهِ.
You have certainly known that I am the most rightful of all others for the Caliphate. By Allāh, so long as the affairs of Muslims remain intact and there is no oppression in it save on myself I shall keep quiet seeking reward for it (from Allāh) and keeping aloof from its attractions and allurements for which you aspire.
