SHAFAQNA – My son, remember four things and by acting on them you will not be hurt.
1. Do not befriend the ignorant because despite wanting to be useful to you, he/she will inflict loss on you.
2. Do not befriend ungenerous person because what you need most, he/she will withhold from you.
3. Do not befriend immoral person because will sell you for a small price.
4. Do not befriend liar because he/she is like a mirage, will show you the remote as close and close as remote .
