Surely silence can sometimes be the most eloquent reply
-Sayyidina Ali ibn Thalib r.a.-
This is one of the interesting point in the book that I read now,(as promised to share with you), Don't be Sad (La Tahzan) by 'Aaidh ibn Abdullah al-Qarni (page 34-35) on how to deal with bitter criticism.
The important point in this excerpt is:
1) Turn away
2) Dismiss the criticism
- it increase our value and merit.
Still practicing it to achieve maximum optimism. InsyaAllah hopefully Allah grant me with preserverance and persistent.
