Safwan bin Umaya sent him to the Messenger of Allah ﷺ with milk, a young gazelle, and small cucumbers, while the Prophet ﷺ was in the upper part of Makkah. He said, "I entered without giving the greeting of peace, so he told me, 'Go back and say, Peace be upon you.'" This was after Safwan bin Umaya had embraced Islam.
أن صفوان بن أمية بعثه إلى رسول الله ﷺ بلبن وجداية وضغابيس، والنبي ﷺ بأعلى مكة، فدخلت، ولم أسلم فقال: ارجع فقل: السلام عليكم، وذاك بعد ما أسلم صفوان بن أمية.
Abu Dawud (5176), Tirmidhi (2710), Nasai in Al-Kubra (6702), and Ahmad (15425) all narrated it through routes going back to Ibn Jurayj, who said, Amr bin Abu Sufyan informed me, that Amr bin Abdullah bin Safwan informed him, that Kalada bin Hanbal informed him, and he related it.They added at the end, Amr (meaning Amr bin Abu Sufyan) said, and Umaya bin Safwan informed me of this hadith from Kalada bin Hanbal, but he did not say, "I heard it from Kalada."Its chain is hasan because of Amr bin Abdullah, for his hadith is hasan. Tirmidhi said, "This is a hasan gharib hadith, we do not know it except through the report of Ibn Jurayj." He also said, "Dighabis are a type of edible plant." In Nihayah it says, they are small cucumbers, the singular of which is dighbus.
