Hisnul Muslim 231

The etiquette of praising a fellow Muslim

قال صلى الله عليه وسلم : " إذا كان أحدكم مادحاً صاحبه لا محالة فليقل : أحسبُ فلاناً والله حسيبهُ ولا أزكي على الله أحداً ، أحسبهُ – إن كان يعلم ذاك – كذا وكذا "

The Prophet (SAW) said: "If any of you praises his companion then let him say: "I deem so-and-so (person's name) to be... And Allah is his Assessor and I don't praise anyone, putting it forward, in front of Allah's commendation, however I assume him so and so ...if he knows that of him".
