حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ عَمْرِو بْنِ مُرَّةَ، عَنْ سَالِمٍ، عَنْ أُمِّ الدَّرْدَاءِ، عَنْ أَبِي الدَّرْدَاءِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَلاَ أُخْبِرُكُمْ بِأَفْضَلَ مِنْ دَرَجَةِ الصِّيَامِ وَالصَّلاَةِ وَالصَّدَقَةِ ‏"‏ ‏.‏ قَالُوا بَلَى ‏.‏ قَالَ ‏"‏ إِصْلاَحُ ذَاتِ الْبَيْنِ وَفَسَادُ ذَاتِ الْبَيْنِ الْحَالِقَةُ ‏"‏ ‏.‏
Translation
Umm Kulthum, daughter of ‘Uqbah, said

I did not hear the Messenger of Allah (ﷺ) making a concession for anything people say falsely except in three matters. The Messenger of Allah (ﷺ) would say: I do not count as a liar a man who puts things right between people, saying a word by which he intends only putting things right, and a man who says something in war, and a man who says something to his wife, or a wife who says something to her husband.
