Sahih Bukhari Volume 2, Book 23, Hadith 1305

حَدَّثَنَا أَصْبَغُ، عَنِ ابْنِ وَهْبٍ، قَالَ أَخْبَرَنِي عَمْرٌو، عَنْ سَعِيدِ بْنِ الْحَارِثِ الأَنْصَارِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ اشْتَكَى سَعْدُ بْنُ عُبَادَةَ شَكْوَى لَهُ فَأَتَاهُ النَّبِيُّ صلى الله عليه وسلم يَعُودُهُ مَعَ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ وَسَعْدِ بْنِ أَبِي وَقَّاصٍ وَعَبْدِ اللَّهِ بْنِ مَسْعُودٍ ـ رضى الله عنهم ـ فَلَمَّا دَخَلَ عَلَيْهِ فَوَجَدَهُ فِي غَاشِيَةِ أَهْلِهِ فَقَالَ ‏"‏ قَدْ قَضَى ‏"‏‏.‏ قَالُوا لاَ يَا رَسُولَ اللَّهِ‏.‏ فَبَكَى النَّبِيُّ صلى الله عليه وسلم فَلَمَّا رَأَى الْقَوْمُ بُكَاءَ النَّبِيِّ صلى الله عليه وسلم بَكَوْا فَقَالَ ‏"‏ أَلاَ تَسْمَعُونَ إِنَّ اللَّهَ لاَ يُعَذِّبُ بِدَمْعِ الْعَيْنِ، وَلاَ بِحُزْنِ الْقَلْبِ، وَلَكِنْ يُعَذِّبُ بِهَذَا ـ وَأَشَارَ إِلَى لِسَانِهِ ـ أَوْ يَرْحَمُ وَإِنَّ الْمَيِّتَ يُعَذَّبُ بِبُكَاءِ أَهْلِهِ عَلَيْهِ ‏"‏‏.‏ وَكَانَ عُمَرُ ـ رضى الله عنه ـ يَضْرِبُ فِيهِ بِالْعَصَا، وَيَرْمِي بِالْحِجَارَةِ وَيَحْثِي بِالتُّرَابِ‏

Narrated By 'Abdullah bin 'Umar : Sad bin 'Ubada became sick and the Prophet along with 'Abdur Rahman bin 'Auf, Sad bin Abi Waqqas and 'Abdullah bin Masud visited him to enquire about his health. When he came to him, he found him surrounded by his household and he asked, "Has he died?" They said, "No, O Allah's Apostle." The Prophet wept and when the people saw the weeping of Allah's Apostle (p.b.u.h) they all wept. He said, "Will you listen? Allah does not punish for shedding tears, nor for the grief of the heart but he punishes or bestows His Mercy because of this." He pointed to his tongue and added, "The deceased is punished for the wailing of his relatives over him." 'Umar used to beat with a stick and throw stones and put dust over the faces (of those who used to wail over the dead).
