The following is the insightful advice of our Respected Founder & Ameer; Hazrat Moulana Haroon Abasoomar (rahimahullah):
When hearing the news of the death of a fellow Muslim, do the following:

1️⃣Recite: inna lillahi wa inna ilayhi raji’un
‎إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ
2️⃣Make du’a for forgiveness for the deceased.
3️⃣Make du’a for the family to be blessed with patience.
4️⃣Make du’a for a good death for ourselves.
5️⃣Do isal thawab for the deceased.
6️⃣Whenever you think of the deceased, immediately make du’a [& isaal thawab] for them.
7️⃣Attend the funeral, if it is within reasonable distance.

🤲🏼 May Allah Ta’ala bless all the Marhumin with complete forgiveness & Jannatul Firdaws.
