Mishkat al-Masabih, 382

Abu Ayyub reported God’s messenger as saying, “Four characteristics pertain to the practices of the messengers:

modesty (but some say circumcision), the use of perfume, the use of the tooth-stick, and marriage.” Tirmidhi transmitted it.

وَعَنْ أَبِي أَيُّوبَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:

أَرْبَعٌ مِنْ سُنَنِ الْمُرْسَلِينَ: الْحَيَاءُ وَيُرْوَى الْخِتَانُ وَالتَّعَطُّرُ وَالسِّوَاكُ وَالنِّكَاحُ

. رَوَاهُ التِّرْمِذِيّ
