Al-Adab Al-Mufrad, Book 48, Hadith 1182 (English)

Salim ibn Jabir al-Hujaymi said, "I came up to the Prophet, may Allah bless him and grant him peace, when he was wrapped up in a cloak whose edges were cover his feet. I said, 'Messenger of Allah, advise me.' He said, 'You must have fearful awareness of Allah. Do not scorn anything correct, even pouring water from your bucket into the bucket of someone else who asks you for water or talking to your brother with a happy face. Beware of dragging your waist-wrapper - it is part of arrogance and Allah does not like it. If a man blames you for something he knows about you, do not blame him for anything you know of him. Leave him to his own evil. You will have your reward. Do not abuse anything.'"

حَدَّثَنَا عَبْدُ اللهِ بْنُ مُحَمَّدٍ، قَالَ‏:‏ حَدَّثَنَا وَهْبُ بْنُ جَرِيرٍ، قَالَ‏:‏ حَدَّثَنَا قُرَّةُ بْنُ خَالِدٍ قَالَ‏:‏ حَدَّثَنِي قُرَّةُ بْنُ مُوسَى الْهُجَيْمِيُّ، عَنْ سُلَيْمِ بْنِ جَابِرٍ الْهُجَيْمِيِّ قَالَ‏:‏ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم وَهُوَ مُحْتَبٍ فِي بُرْدَةٍ، وَإِنَّ هُدَّابَهَا لَعَلَى قَدَمَيْهِ، فَقُلْتُ‏:‏ يَا رَسُولَ اللهِ، أَوْصِنِي، قَالَ‏:‏ عَلَيْكَ بِاتِّقَاءِ اللهِ، وَلاَ تَحْقِرَنَّ مِنَ الْمَعْرُوفِ شَيْئًا، وَلَوْ أَنْ تُفْرِغَ لِلْمُسْتَسْقِي مِنْ دَلْوِكَ فِي إِنَائِهِ، أَوْ تُكَلِّمَ أَخَاكَ وَوَجْهُكَ مُنْبَسِطٌ، وَإِيَّاكَ وَإِسْبَالَ الإِزَارِ، فَإِنَّهَا مِنَ الْمَخِيلَةِ، وَلاَ يُحِبُّهَا اللَّهُ، وَإِنِ امْرُؤٌ عَيَّرَكَ بِشَيْءٍ يَعْلَمُهُ مِنْكَ فَلاَ تُعَيِّرْهُ بِشَيْءٍ تَعْلَمُهُ مِنْهُ، دَعْهُ يَكُونُ وَبَالُهُ عَلَيْهِ، وَأَجْرُهُ لَكَ، وَلاَ تَسُبَّنَّ شَيْئًا‏.‏
