Hadith.2664 - It was narrated from Al-Hasan ibn Ziyad, who said
I said to Abu Abdullah (as): "My servant poured water for me to perform ablution, and I was unaware that there was fragrance (dustashan) in it. I then washed my hands while I was in Ihram."
Imam (as) said: "Give something in charity as an expiation for that."
