(2) In one of your fatwa you suggested to write down ayat on a boiled egg so please guide how to write down ayat on the boiled egg. Should it be with a pen or with a finger? And I kindly request you to please make a dua for me and my family.
بسم الله الرحمن الرحيم
رَبَّنَا هَبْ لَنَا مِنْ أَزْوَاجِنَا وَذُرِّيَّاتِنَا قُرَّةَ أَعْيُنٍ وَاجْعَلْنَا لِلْمُتَّقِينَ إِمَاماً
Ask your sister and her husband to recite the above mentioned dua 3 times after each salah with durood 3-3 times before and after, as well while going to bed.
(2) Write it with a pen.
Allah knows Best!
