You are requested to perform namaaz-e-wahshat for the marhum tonight between Maghrib and Isha Prayers.
How to perform namaaz-e-Wahshat?
It is Mustahab that on the day of the burial on this night between Maghrib and Isha one should recite two rak'ats prayer. This is known as Namaz-e-Wahshat because for the dead person the most horrifying and difficult is the first night. In the first rak'at after Surah Hamd recite Ayatul Kursi and in the second rak'at after Surah Hamd recite Surah Qadr 10 times. After finishing the prayers mention the name of the dead person and gift him/her the Sawab of this namaaz.
