عَنِ الْخَضْرَمِيِّ بْنِ لَاحِقٍ عَنْ رَجُلٍ مِنَ الْأَنْصَارِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((إِذَا وَجَدَ أَحَدُكُمُ الْقَمْلَةَ فِي ثَوْبِهِ فَلْيَصُرَّهَا وَلَا يُلْقِهَا فِي الْمَسْجِدِ))
Hazrami bin Lahiq narrates from an Ansari man that the Messenger of Allah, peace and blessings be upon him, said: When any of you feels a louse in his garment, he should press it and not throw it in the mosque.
