Narrated Shaqiq bin Salama:
I was sitting with Abu Mas'ud and Abu Musa and 'Ammar. Abu Mas'ud said (to 'Ammar), "There is none of your companions but, if I wish, I could find fault with him except with you. Since you joined the company of the Prophet I have never seen anything done by you more criticizable by me than your haste in this issue." 'Ammar said, O Abu Mas'ud ! I have never seen anything done by you or by this companion of yours (i.e., Abu Musa) more criticizable by me than your keeping away from this issue since the time you both joined the company of the Prophet."
Then Abu Mas'ud who was a rich man, said (to his servant), "O boy! Bring two suits." Then he gave one to Abu Musa and the other to 'Ammar and said (to them), "Put on these suits before going for the Friday prayer. "
