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
