We were at Wasit al-Qasab with Abdul-Ala bin Abdullah bin Amir. There was a man with him called Abu Ghadiya who asked for water to drink. He was brought a vessel inlaid with silver and refused to drink from it. He then mentioned the Prophet ﷺ and recounted this hadith, "Do not become disbelievers or misguided people after me," (Ibn Abu Adi was uncertain which word was used) "striking each other's necks."Then a man started cursing so-and-so, so I said, "By Allah, if Allah ever gives me power over you in a battle." On the day of Siffin, I came upon him wearing a coat of mail. I noticed the gap at the collar of the mail and stabbed him through it, killing him. It turned out to be Ammar bin Yasir.I said, "What hands are these of his! He refuses to drink from a vessel inlaid with silver, yet he has killed Ammar bin Yasir."
حدثنا عبد الله قال حدثني أبو موسى العنزي محمد بن المثنى قال حدثنا محمد بن أبي عدي عن ابن عون
كنا بواسط القصب عند عبد الأعلى بن عبد الله بن عامر قال فإذا عنده رجل يقال له أبو الغادية استسقى ماء فأتي بإناء مفضض فأبى أن يشرب وذكر النبي ﷺ فذكر هذا الحديث لا ترجعوا بعدي كفارا أو ضلالا شك ابن أبي عدي يضرب بعضكم رقاب بعض فإذا رجل يسب فلانا فقلت والله لئن أمكنني الله منك في كتيبة فلما كان يوم صفين إذا أنا به وعليه درع قال ففطنت إلى الفرجة في جربان الدرع فطعنته فقتلته فإذا هو عمار بن ياسر قال قلت وأي يد كفتاه يكره أن يشرب في إناء مفضض وقد قتل عمار بن ياسر
Its chain is hasan, on account of Kulthum bin Jabr, who was graded reliable by Ahmad, Ibn Main, Ibn Hibban, and Hamza Nasai. The marfu portion of the hadith was narrated by Bukhari 1/217, no. 121, Muslim 1/81, no. 65, Tirmidhi 4/486, no. 2193, who said it is hasan sahih, Nasai 1/126, no. 4125, and Ibn Majah 2/1300, no. 3943. The hadith here is from the additions of Abdullah.
