[Machine] The following translation is a saying I heard from the Messenger of Allah ﷺ :

"Verily, the slightest form of showing off is a form of polytheism (shirk). And the most beloved of Allah's servants are the most pious ones who hide their good deeds and qualities. They are those who, when absent, are not missed, and when present, are not acknowledged. They are the leaders of guidance and the torchbearers of knowledge."

This hadith has a sahih (authentic) chain of narration and wasn't narrated by Abu Qahtham. Abu Hatim said his hadith should not be written down, and Al-Nasa'i considered his trustworthiness doubtful.  

حَدِيثٌ سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ﷺ «إِنَّ أَدْنَى الرِّيَاءِ شِرْكٌ وَأَحَبَّ الْعَبِيدِ إِلَى اللَّهِ تَبَارَكَ وَتَعَالَى الْأَتْقِيَاءُ الْأَخْفِيَاءُ الَّذِينَ إِذَا غَابُوا لَمْ يُفْتَقَدُوا وَإِذَا شَهِدُوا لَمْ يُعْرَفُوا أُولَئِكَ أَئِمَّةُ الْهُدَى وَمَصَابِيحُ الْعِلْمِ» صَحِيحُ الْإِسْنَادِ وَلَمْ يُخَرِّجَاهُ أبو قحذم قال أبو حاتم لا يكتب حديثه وقال النسائي ليس بثقة  

[Machine] I heard a saying from the companion of this grave, meaning the Prophet ﷺ, "Indeed, the slightest form of showing off is shirk (associating partners with Allah), and the most beloved of servants to Allah are the most pious ones who hide their piety. They are the ones who, when they are absent, are not missed, and when they are present, they are not known. They are the leaders of guidance and the illuminating lamps of knowledge."  

حَدِيثٌ سَمِعْتُهُ مِنْ صَاحِبِ هَذَا الْقَبْرِ يَعْنِي النَّبِيَّ ﷺ «إِنَّ أَدْنَى الرِّيَاءِ شِرْكٌ وَأَحَبُّ الْعَبِيدِ إِلَى اللهِ الْأَتْقِيَاءُ الْأَخْفِيَاءُ الَّذِينَ إِذَا غَابُوا لَمْ يُفْتَقَدُوا وَإِذَا شَهِدُوا لَمْ يُعْرَفُوا أُولَئِكَ أَئِمَّةُ الْهُدَى وَمَصَابِيحُ الْعِلْمِ»  

"أحبُّ العباد إلى اللهِ ﷻ: الأتقياءُ الأخفياء الذين إذا غابوا لم يُفْتَقَدوا، وإذا شوهدوا لم يعرفوا، أولئك أئمة الهدى، ومصابيحُ العلم".
