Narrated Al-Mughirah ibn Shu'bah:

One night I became the guest of the Prophet ﷺ. He ordered that a piece of mutton be roasted, and it was roasted. He then took a knife and began to cut the meat with it for me. In the meantime Bilal came and called him for prayer. He threw the knife and said: What happened! may his hands be smeared with earth! He then stood for offering prayer. Al-Anbari added: My moustaches became lengthy. He trimmed them by placing a took-stick; or he said: I shall trim your moustaches by placing the tooth-stick there.

Al-Anbari said: My moustaches became lengthy. He trimmed them by placing a tooth-stick ; or he said: I shall trim your moustaches by placing the tooth-stick there.

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ سُلَيْمَانَ الأَنْبَارِيُّ، - الْمَعْنَى - قَالاَ حَدَّثَنَا وَكِيعٌ، عَنْ مِسْعَرٍ، عَنْ أَبِي صَخْرَةَ، جَامِعِ بْنِ شَدَّادٍ عَنِ الْمُغِيرَةِ بْنِ عَبْدِ اللَّهِ، عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، قَالَ ضِفْتُ النَّبِيَّ ﷺ ذَاتَ لَيْلَةٍ فَأَمَرَ بِجَنْبٍ فَشُوِيَ وَأَخَذَ الشَّفْرَةَ فَجَعَلَ يَحُزُّ لِي بِهَا مِنْهُ - قَالَ - فَجَاءَ بِلاَلٌ فَآذَنَهُ بِالصَّلاَةِ - قَالَ - فَأَلْقَى الشَّفْرَةَ وَقَالَ " مَا لَهُ تَرِبَتْ يَدَاهُ " . وَقَامَ يُصَلِّي . زَادَ الأَنْبَارِيُّ وَكَانَ شَارِبِي وَفَى فَقَصَّهُ لِي عَلَى سِوَاكٍ . أَوْ قَالَ أَقُصُّهُ لَكَ عَلَى سِوَاكٍ .
