Riyad as-Salihin, Book 18, Hadith 1797 (In-Book) ⓘ

Anas bin Sirin (May Allah be pleased with him) said: I was with Anas bin Malik (May Allah be pleased with him) in the company of some Magians when Faludhaj (a sweet made of flour and honey) was brought in a silver utensil, and Anas did not take it. The man was told to change the utensil. So he changed the utensil and when he brought it to Anas, he took it.[Al-Baihaqi].

وعن أنس بن سيرين قال‏:‏ كنت مع أنس بن مالك رضي الله عنه عند نفر من المجوس، فجيء بفالوذج على إناء من فضة، فلم يأكله، فقيل له‏:‏ حوله، فحوله على إناء من خلنج، وجيء به فأكله‏.‏ ‏(‏‏(‏رواه البيهقي بإسناد حسن‏)‏‏)‏‏.‏
