hmmm.... nice advice! Why not to tie a dead black 'murgha' with the silencer pipe!!!!!
On the contrary, I would recommend two things only:
One; Give some money as Sadqa to really needy people, with a prayer in your heart that may you and your car remains safe from all sorts of troubles and accidents. Bad spells of time can only be guarded away with Sadqa, not black cloth pieces!
Two; Drive carefully. Feel the joy and pride of driving a cool car, but don't get proud! You are not the only one driving a good car!
And finally, please select correct words for your thread! At first, I thought your car really fell inside a manhole!! Better was to write your car hit an open manhole.
Anyways, have a safer drive next time. Fee-Amaan-Allah!
