[33:3] And rely on Allah; and Allah is sufficient for a Protector.

[4:132] And whatever is in the heavens and whatever is in the earth is Allah's, and Allah is sufficient as a Protector.

[13:11] For his sake there are angels following one another, before him and behind him, who guard him by Allah's commandment; surely Allah does not change the condition of a people until they change their own condition; and when Allah intends evil to a people, there is no averting it, and besides Him they have no protector.

So Asim dear, I feel keeping taweez with this belief that it will protect you from harm is like keeping a little idol with you, which is a form of SHIRK. The best way is to keep praying to the Lord Almighty for protections , remembering His attributes, reciting different Surahs and Ayaat, Duas and giving Sadaqa are the first-aid kit for a Muslim :)

Thanks for replying me sir my next question is about the wazeefa which we called as a dua sit i am being called to rehearse the phrase (Durrood sharif )80 times after the prayer of friday sir if we increse or decrease the 80 times is there will be any effect on the result of the dua

Do you think Allah 'needs' to take account for 'counts'?

[2:186] And when My servants ask you concerning Me, then surely I am very near; I answer the prayer of the suppliant when he calls on Me, so they should answer My call and believe in Me that they may walk in the right way.

All we need is to 'believe'!

Plz keep it up.

Salam
