Abu Raja reported,
Imran bin Husayn came out to us wearing a silk cloak that we had never seen on him before that day, nor did we see it on him afterward. He said, "The Messenger of Allah ﷺ said, 'When Allah 
bestows a blessing upon someone, Allah loves to see the trace of His blessing upon His creation.'"
Azami 15298
Hasanعن أبي رجاء العطاردي قال
خرج علينا عمران بن حصين، وعليه مطرف من خز، لم نره عليه قبل ذلك ولا بعده، فقال: إن رسول الله ﷺ قال: من أنعم الله عز وجل عليه نعمة، فإن الله عز وجل يحب أن يرى أثر نعمته على خلقه.
Ahmad (19934), Tabarani in Al-Kabir (18/135), and Bayhaqi in Al-Shuab (5789) all narrated it through the hadith of Rawh bin Ubada, who said, Shuba narrated to us, from Fudayl bin Fadala, from Abu Raja Attaradi, who mentioned it.Its chain is hasan because of Fudayl bin Fadala Qaysi Basri, for he is hasan al-hadith. Ibn Main deemed him trustworthy, and Abu Hatim said, "A shaykh."As for his statement "a mitraf of khazz," it means a square cloak of khazz with markings of silk, and this portion of silk is permissible by the unanimous agreement of the scholars.
