حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ جَامِعِ بْنِ شَدَّادٍ، عَنْ كُلْثُومٍ الْخُزَاعِيِّ، قَالَ أَتَى النَّبِيَّ ـ صلى الله عليه وسلم ـ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ كَيْفَ لِي أَنْ أَعْلَمَ إِذَا أَحْسَنْتُ أَنِّي قَدْ أَحْسَنْتُ وَإِذَا أَسَأْتُ أَنِّي قَدْ أَسَأْتُ فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " إِذَا قَالَ جِيرَانُكَ إِنَّكَ قَدْ أَحْسَنْتَ فَقَدْ أَحْسَنْتَ وَإِذَا قَالُوا إِنَّكَ قَدْ أَسَأْتَ فَقَدْ أَسَأْتَ " .
It was narrated that Kulthum Al-Khuza’i said:“A man came to the Prophet (ﷺ) and said: ‘O Messenger of Allah, how can I know, when I have done something good, that I have done well, and if I have done something bad, that I have done a bad deed?’ The Messenger of Allah (ﷺ) said: ‘If your neighbors say that you have done something good, then you have done well, and if they say that you have done something bad, then you have done something bad.’”
