Hazrat Mufti Ebrahim Salejee (Daamat Barakaatuhu) mentioned:
The easiest way to explain adab is that one ensures that others are comfortable and happy.
We have failed miserably when it comes to adab and akhlaaq at home. We might be showing that adab and akhlaaq to others, but how many of us show it to our families, whereas this is where the greatest amount of adab and akhlaaq needs to be shown.
