مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ عَنْ عَبْدِ اللَّهِ بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ كَانَتْ لِرَسُولِ اللَّهِ ( صلى الله عليه وآله ) مَمْسَكَةٌ إِذَا هُوَ تَوَضَّأَ أَخَذَهَا بِيَدِهِ وَ هِيَ رَطْبَةٌ فَكَانَ إِذَا خَرَجَ عَرَفُوا أَنَّهُ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) بِرَائِحَتِهِ .

3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Mahbub from ‘Abd Allah ibn Sinan who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, had a musk container. When making wudu he would take it in his hand while wet. When coming out people noticed his coming because of the perfume and fragrance.’”
