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 from Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Four things are the practices of the Messengers: applying perfume, marrying, using the miswak, and having modesty.
