Assalam aleikum sidi i am um obada, i hope you are well in sha Allah. Ya sidi, till now i didnt manage to talk about religion with my grand parents.i havent seen them for 2 years and on the phone they just talk about their everyday life and i dont know how to introduce the subject. they are not intellectual and even if they are catholic they are not religious and they dont have a strong belief in God. Please make duas and advise me i must say something to them. wallahi i should thank Allah day and night for becoming muslim and having you as my sheikh. و جزاكم ربي كل خير و صلى الله على سيدنا و حبيبينا محمد. الله يحفظكم و يجمعنا في الدنيا و الآخرة..دعواتكم

May  ALLAH  bless you and all your family ...
iam happy for your care of your grand parents  , so what you have to know that ALLAH guide whom he will to the faith but you have to  do the best  ways to effect them and be patient and may ALLAH help you and keep you at his prophet heart
