Abu Saʼid al-Xudriy rivoyat qiladi: musulmonlar Madinadagi masjidni qurayotganlarida, ʼAmmor ibn Yosir ikki donadan g‘isht ko‘tarardi, boshqalar esa bittadan ko‘tarardi. Payg‘ambar ﷺ uni ko‘rib, ʼAmmorning ustidagi changni qo‘llari bilan artishni boshladi va dedi: “Voy ʼAmmorga! Uni ta’magir guruh o‘ldiradi. U ularni Jannatga chaqiradi, ular esa uni Do‘zaxga chaqiradilar.” Shunga javoban ʼAmmor dedi: “Fitnalardan Allohga panoh tilaymiz.”297 Bu bashoratdan o‘ttiz yil o‘tib, Siffin jangi bo‘lib o‘tdi. Shu jangda ʼAmmor, o‘ldirilgan xalifa ʼUsmonning qasosini olishni istagan Shom lashkari tomonidan o‘ldirildi, ular musulmonlarning hokimi ʼAliga qarshi tajovuz qilgan edilar. Qizig‘i shundaki, Shom lashkari bu hadisni soxtalashtirilgan deb da’vo qilmadi, balki uni chaqirgan kishilarni, ya’ni uning o‘limi uchun oxir-oqibat javobgar bo‘lgan “ta’magir guruh”ni ayblab chiqdi.

Abū Sa‘īd al-Khudrī  narrated that, as the Muslims were building the mosque in Madinah, ‘Ammār ibn Yāsir  would carry two bricks at a time while others lifted one. When the Prophet صلى الله عليه وسلم saw him, he began wiping the dust off ‘Ammār with his hands and said, “Woe to ‘Ammār, who will be killed by the transgressing party! He will be inviting them to Paradise, and they will be inviting him to the Fire.” To that, ‘Ammār replied, “We seek refuge with Allah from the trials.”297 Three decades after that prophecy, when the Battle of Ṣiffīn took place, ‘Ammār was killed by the army of Shām who transgressed against the Muslim ruler, ‘Alī, while seeking to avenge the murdered caliph, ‘Uthmān. Interestingly, the army of Shām did not claim that this hadith had been fabricated, but rather argued that those who called him to fight were the “transgressing party” ultimately responsible for his death.
