How a muslim should praise another muslim

If any of you praises his companion then let him say: I consider (such and such a person) to be, and Allah is his Assessor, and I don’t praise anyone, putting it [i.e.,my praising] forward, in front of Allah’s commendation - if you know of this (good character trait in the person) to be such and such (saying what he thinks is praiseworthy in that person).
