عَنْ أَبِي أَيُّوبَ الْأَنْصَارِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَرْبَعٌ مِنْ سُنَنِ الْمُرْسَلِينَ التَّعَطُّرُ وَالنِّكَاحُ وَالسِّوَاكُ وَالْحَيَاءُ
Narrated by Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Four things are the practices of the noble Prophets: applying perfume, marriage, using the miswak, and living life with modesty.
