Abu Musa and Abii Masʿud went to ʿAmmar when ʿAli had sent him to Kufa to exhort them to fight (on ʿAli's side). They said to him, "Since you have become a Muslim, we have never seen you doing a deed more criticizable to us than your haste in this matter." ʿAmmar said, "Since you (both) became Muslims, I have never seen you doing a deed more criticizable to me than your keeping away from this matter." Then Abu Masʿud provided ʿAmmar and Abu Musa with two-piece outfits to wear, and one of them went to the mosque (of Kufa).  

سَمِعْتُ أَبَا وَائِلٍ يَقُولُ دَخَلَ أَبُو مُوسَى وَأَبُو مَسْعُودٍ عَلَى عَمَّارٍ حَيْثُ بَعَثَهُ عَلِيٌّ إِلَى أَهْلِ الْكُوفَةِ يَسْتَنْفِرُهُمْ فَقَالاَ مَا رَأَيْنَاكَ أَتَيْتَ أَمْرًا أَكْرَهَ عِنْدَنَا مِنْ إِسْرَاعِكَ فِي هَذَا الأَمْرِ مُنْذُ أَسْلَمْتَ فَقَالَ عَمَّارٌ مَا رَأَيْتُ مِنْكُمَا مُنْذُ أَسْلَمْتُمَا أَمْرًا أَكْرَهَ عِنْدِي مِنْ إِبْطَائِكُمَا عَنْ هَذَا الأَمْرِ وَكَسَاهُمَا حُلَّةً حُلَّةً ثُمَّ رَاحُوا إِلَى الْمَسْجِدِ  

[Machine] "Abu Musa Al-Ash'ari and Abu Masood Al-Badri entered upon Ammar while he was agitating the people. They said to him, 'We have not seen anything from you since you embraced Islam that we disliked more than your hastiness in this matter.' Ammar replied, 'I have not witnessed anything from the two of you since you embraced Islam that I disliked more than your delay in this matter.' Ammar then covered them with clothes and went out to perform the Friday prayer."
