Explanation & Benefits
Shaykh Muhammad Ibrahim bin Basheer
Benefit: The virtue of saying "Jazak Allah" is mentioned in this hadith. In life, every person is in need of others, so whenever someone does a good deed, one should respond by saying "Jazak Allah." This encourages the person, and through this phrase, praising someone for acts of goodness is also established. However, praise that involves exaggeration is absolutely forbidden, whether the person being praised is present or not.
