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. (Using translation from Abū Dāʾūd 188)
بِتُّ بِرَسُولِ اللهِ ﷺ ذَاتَ لَيْلَةٍ فَأَمَرَ بِجَنْبٍ فَشُوِيَ ثُمَّ أَخَذَ الشَّفْرَةَ فَجَعَلَ يَحُزُّ لِي بِهَا مِنْهُ فَجَاءَ بِلَالٌ يُؤْذِنُهُ بِالصَّلَاةِ فَأَلْقَى الشَّفْرَةَ وَقَالَ مَا لَهُ تَرِبَتْيَدَاهُ؟ قَالَ وَكَانَ شَارِبِي وَفَى فَقَصَّهُ لِي عَلَى سِوَاكٍ أَوْ قَالَ أَقُصُّهُ لَكَ عَلَى سِوَاكٍ
