Nahj al-Balāgha
Hadith 1031وَالْسَّلاَمُ عَلَيْكُمَا سَلاَمَ مُوَدِّع، لاَ قَال وَلاَ سَئم، فَإنْ أَنْصَرِفْ فَلاَ عَنْ مَلاَلَة، وَإِنْ أُقِمْ فَلاَ عَنْ سُوءِ ظَنٍّ بِمَا وَعَدَ اللهُ الصَّابِرِينَ.
My salām (salutation) be on you both, the salutation of one bidding farewell, neither in aversion nor in dislike, for if I go away it is not because I am weary (of you), and if I stay it is not due to lack of belief in what Allāh has promised the endurers.
