Very effective amal for a pious child:
If someone wishes to have a pious child then he should do the following amal:
On the 1st Friday of the month of Ramadhaan, after the jumuah salaah one should write 100 times يا احد on a blank piece of paper and make into a Taweez. He should then wear it on his right arm. Insha Allah within that year he will be blessed with a pious child.
