وَعَن أَنس
قَالَ: وُقِّتَ لَنَا فِي قَصِّ الشَّارِبِ وَتَقْلِيمِ الْأَظْفَارِ وَنَتْفِ الْإِبِطِ وَحَلْقِ الْعَانَةِ أَنْ لَا تُتْرَكَ أَكثر من أَرْبَعِينَ لَيْلَة
Anas said they were told not to let more than forty days elapse between the times they clipped the moustache, pared the nails, plucked out hairs under the armipits and shaved the pubes.
