How a Muslim should praise another Muslim

قَالَ النَّبِيُّ صلى الله عليه وسلم: ((إِذَا كَانَ أَحَدُكُم مَادِحاً صَاحِبَهُ لاَ مَحَالَةَ فَلْيَقُلْ: أَحْسِبُ فُلاَناً وَاللَّهُ حَسِيبُهُ، وَلاَ أُزَكِّي عَلَى اللَّهِ أَحَداً، أَحْسِبُهُ – إِنْ كَانَ يَعْلَمُ ذَاكَ – كَذَا وَكَذَا)).

(He said: ‘If anyone of you is impelled to praise his brother, then he should say: ‘I deem so-and-so to be…and Allah is his reckoner…and I don’t praise anyone, putting it (i.e. my praising) forward, in front of Allah’s commendation, however I assume him so and so’…if he knows that of him.)
