Sunan Ibn Majah Book 36, Hadith 3989

حَدَّثَنَا حَرْمَلَةُ بْنُ يَحْيَى، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي ابْنُ لَهِيعَةَ، عَنْ عِيسَى بْنِ عَبْدِ الرَّحْمَنِ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ أَبِيهِ، عَنْ عُمَرَ بْنِ الْخَطَّابِ، أَنَّهُ خَرَجَ يَوْمًا إِلَى مَسْجِدِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فَوَجَدَ مُعَاذَ بْنَ جَبَلٍ قَاعِدًا عِنْدَ قَبْرِ النَّبِيِّ ـ صلى الله عليه وسلم ـ يَبْكِي فَقَالَ مَا يُبْكِيكَ قَالَ يُبْكِينِي شَىْءٌ سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ سَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ ‏ "‏ إِنَّ يَسِيرَ الرِّيَاءِ شِرْكٌ وَإِنَّ مَنْ عَادَى لِلَّهِ وَلِيًّا فَقَدْ بَارَزَ اللَّهَ بِالْمُحَارَبَةِ إِنَّ اللَّهَ يُحِبُّ الأَبْرَارَ الأَتْقِيَاءَ الأَخْفِيَاءَ الَّذِينَ إِذَا غَابُوا لَمْ يُفْتَقَدُوا وَإِنْ حَضَرُوا لَمْ يُدْعَوْا وَلَمْ يُعْرَفُوا قُلُوبُهُمْ مَصَابِيحُ الْهُدَى يَخْرُجُونَ مِنْ كُلِّ غَبْرَاءَ مُظْلِمَةٍ ‏"‏ ‏.‏

It was narrated from ‘Umar bin Khattab that he went out one day to the mosque of the Messenger of Allah (ﷺ), and he found Mu’adh bin Jabal sitting by the grave of the Prophet (ﷺ), weeping. He said:“Why are you weeping?” He said: “I am weeping because of something that I heard from the Messenger of Allah (ﷺ). I heard the Messenger of Allah (ﷺ) say: ‘A little showing off is polytheism and whoever shows enmity towards a friend of Allah has declared war on Allah. Allah loves those who se righteousness and piety are hidden, those who, if they are absent, are not missed, and if they are present, they are not invited or acknowledged. Their hearts are lamps of guidance and they get out of every trial and difficulty.’”
