Qurʾān Bukhārī Muslim Nasāʾī Abū Dāwūd Tirmidhī Ibn Mājah Mālik Aḥmad Dārimī Ḥākim Ibn Ḥibbān Ṭabarānī Nasāʾī's Kubrá Bayhaqī al-Luʾluʾ wa-al-Marjān Ibn Rajab's Fifty Riyāḍ al-Ṣāliḥīn Aḥmad's Zuhd Suyūṭī
tabarani:14237 – ʿAlī b. ʿAbd al-ʿAzīz > ʿAbdullāh b. Muḥammad al-Ḍabbī > Ḥammād b. Salamah > Abū Jaʿfar al-Khaṭmī

[Machine] His grandfather was 'Umayr ibn Habib ibn Khumashah. He pledged allegiance to the Prophet ﷺ in a dream and advised his son, saying, "Beware of keeping company with foolish people, as their company is a disease. Whoever avoids being deluded by foolish people will be content with his patience, and whoever loves them will regret it. Whoever does not accept a small harm from a fool will accept a great harm. Whoever endures what he dislikes will attain what he loves. And when one of you wants to command good or prohibit evil, let him be patient in the face of harm and have faith in the reward from Allah, for whoever has faith in the reward from Allah will not be affected by harm."  

الطبراني:١٤٢٣٧ – حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ الْعَزِيزِ ثَنَا عَبْدُ اللهِ بْنُ مُحَمَّدٍ الضَّبِّيُّ ثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ أَبِي جَعْفَرٍ الْخَطْمِيِّ

أَنَّ جَدَّهُ عُمَيْرَ بْنَ حَبِيبِ بْنِ خُمَاشَةَ كَانَتْ لَهُ صُحْبَةٌ بَايَعَ النَّبِيَّ ﷺ عِنْدَ احْتِلَامِهِ وَأَوْصَى وَلَدَهُ فَقَالَ «إِيَّاكَ وَمُجَالَسَةَ السُّفَهَاءِ فَإِنَّ مُجالَسَتَهُمْ دَاءٌ مَنْ تَحَلَّمَ عَنِ السَّفِيهِ يُسَرُّ بِحِلْمِهِ وَمَنْ يُحِبَّهُ يَنْدَمْ وَمَنْ لَا يُقِرَّ بِالْقَلِيلِ مِمَّا يَأْتِي بِهِ السَّفِيهُ يُقَرَّ بِالْكَثِيرِ وَمَنْ يَصْبِرْ عَلَى مَا يَكْرَهُ يُدْرِكْ مَا يُحِبُّ وَإِذَا أَرَادَ أَحَدُكُمْ أَنْ يَأْمُرَ بِمَعْرُوفٍ أَوْ يَنْهَى عَنْ مُنْكَرٍ فَلْيُوَطِّنْ نَفْسَهُ بِالصَّبِرِ عَلَى الْأَذَى ولْيَثِقْ بِالثَّوَابِ مِنَ اللهِ ﷻ فَإِنَّهُ مَنْ يَثِقْ بِالثَّوَابِ مِنَ اللهِ لَا يَجِدُ مَسَّ الْأَذَى»

[Machine] His grandfather was Umayr ibn Habib, and he had already pledged allegiance to the Prophet ﷺ . He advised his sons, saying, "O my sons, beware of associating with fools, for their companionship is a disease. Whoever is patient with them will be pleased with his patience, and whoever responds to them will regret it. And whoever does not agree with a little of what the fool brings, will agree with much. And when any of you wants to command good and forbid evil, let him strengthen himself before that against harm, and let him have certainty in the reward from Allah. For whoever has certainty in the reward from Allah, will not feel the harm."  

البيهقي:٢٠٢١٠ – أَخْبَرَنَا أَبُو الْحُسَيْنِ بْنُ بِشْرَانَ ثنا أَبُو عَمْرِو بْنُ السَّمَّاكِ ثنا حَنْبَلُ بْنُ إِسْحَاقَ ثنا مُسْلِمُ بْنُ إِبْرَاهِيمَ ثنا حَمَّادُ بْنُ سَلَمَةَ ثنا أَبُو جَعْفَرٍ الْخَطْمِيُّ

أَنَّ جَدَّهُ عُمَيْرَ بْنَ حَبِيبٍ وَكَانَ قَدْ بَايَعَ النَّبِيَّ ﷺ أوَصَى بَنِيهِ قَالَ لَهُمْ أَيْ بَنِيَّ إِيَّاكُمْ وَمُخَالَطَةَ السُّفَهَاءِ فَإِنَّ مُجَالَسَتَهُمْ دَاءٌ وَإِنَّهُ مَنْ يَحْلُمْ عَنِ السَّفِيهِ يُسَرَّ بِحِلْمِهِ وَمَنْ يُجِبْهُ يَنْدَمْ وَمَنْ لَا يُقِرَّ بِقَلِيلِ مَا يَأْتِ بِهِ السَّفِيهُ يُقِرُّ بِالْكَثِيرِ وَإِذَا أَرَادَ أَحَدُكُمْ أَنْ يَأْمُرَ بِالْمَعْرُوفِ وَيَنْهَى عَنِ الْمُنْكَرِ فَلْيُوَطِّنْ نَفْسَهُ قَبْلَ ذَلِكَ عَلَى الْأَذَى وَلْيُوقِنْ بِالثَّوَابِ مِنَ اللهِ فَإِنَّهُ مَنْ يُوقِنْ بِالثَّوَابِ مِنَ اللهِ لَا يَجِدُ مَسَّ الْأَذَى

[Machine] "O my children, beware of associating with the foolish, for their companionship is a disease. Whoever dreams about a fool does not see with his dream. And whoever does not escape from a little harm caused by a fool, will eventually have to escape from a major harm. And whoever endures what he dislikes will attain what he loves. And when one of you intends to enjoin what is good and forbid what is evil upon people, let him prepare himself for enduring harm, and let him be certain of the reward from Allah. For indeed, whoever has confidence in the reward from Allah will not feel the affliction."  

الزهد لأحمد:١٠٣١ – حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي أَبِي حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ أَنْبَأَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ جَعْفَرٍ الْخَطَمِيِّ أَنَّ جَدَّهُ عُمَيْرَ بْنَ حَبِيبٍ أَوْصَى بَنِيهِ وَكَانَتْ لَهُ صُحْبَةٌ فَقَالَ

«يَا بَنِيَّ إِيَّاكُمْ وَمُجَالَسَةَ السُّفَهَاءِ فَإِنَّ مُجَالَسَتَهُمْ دَاءٌ إِنَّهُ مَنْ يَحْلُمُ عَنِ السَّفِيهِ لَيْسَ يَنْظُرُ بِحِلْمِهِ وَمَنْ لَا يَفِرُّ بِقَلِيلِ مَا يَأْتِي بِهِ السَّفِيهُ يَفِرُّ بِالْكَبِيرِ وَمَنْ يَصْبِرْ عَلَى مَا يَكْرَهُ يُدْرِكْ مَا يُحِبُّ وَإِذَا أَرَادَ أَحَدُكُمْ أَنْ يَأْمُرَ النَّاسَ بِالْمَعْرُوفِ وَيَنْهَاهُمْ عَنِ الْمُنْكَرِ فَلْيُوَطِّنْ نَفْسَهُ عَلَى الصَّبْرِ عَلَى الْأَذَى وَلْيُوقِنْ بِالثَّوَابِ مِنَ اللَّهِ فَإِنَّهُ مَنْ يَثِقْ بِالثَّوَابِ مِنَ اللَّهِ لَا يَجِدُ مَسَّ الْأَذَى»
