ponder on exactly what ?
this is what the scholars suggest as a part of TAQWA , not as a FATWA .
now u should know well the difference between a FATWA and a TAQWA.
if you dont let me explain by an incident ....
there was once a pious person , onec on his way to masjid , he got a bit of impurity on his clothes ,
he washed all his clothes on the nearby pond , and continued on his way ...
a person asked him , that it was such tiny dirt you got on your clothes , we have a FATWA that if the dirt is smaller than a dime , you can pray in those clothes , so why did you wash it on such a little dirt.
he answered , that was FATWA , this is my TAQWA.
so there is no FATWA on giving names on the name of prophets an Allah ( swt) , but just to ensure your emaan on the safest side of TAQWA, this action is recommended , with NO OBLIGATIONS.
hope this answers.
