عَنْ عَبْدِ اللَّهِ بْنِ زَمْعَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ خَطَبَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ثُمَّ وَعَظَهُمْ فِي ضِحْكِهِمْ مِنَ الضَّرْطَةِ فَقَالَ عَلَامَ يَضْحَكُ أَحَدُكُمْ عَلَى مَا يَفْعَلُ
It is narrated from Sayyiduna Abdullah bin Zam’ah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) delivered a sermon and then admonished the people about laughing at passing wind, and said: Why does one of you laugh at something which he himself does?
