How to offer funeral prayer

One should raise both hands just as he does for the takbeer-e-tahreemah. When doing this he should say Allahu Akbar and thereafter tie his hands just as he does for any other prayer. He should then recite Al-Fatiha'. Thereafter, he should say Allahu Akbar again. He should then recite the Al-Salat Al-Ibrahimeyeh (which is Allahumma Salee Aala Mohammad Wa Ala Ali Mohammad Kma Salayta Ala Ibraim, Wa Ala Ali Ibrahim ... until the end). He should again say Allahu Akbar. After this takbeer, he should make dua for the deceased. If the deceased is a mature male or female, the following dua should be made:

اللَّهُمَّ اغْفِرْ لِحَيِّنَا وَمَيِّتِنَا وَشَاهِدِنَا وَغَائِبِنَا وَصَغِيرِنَا وَكَبِيرِنَا وَذَكَرِنَا وَأُنْثَانَا . اللَّهُمَّ مَنْ أَحْيَيْته مِنَّا فَأَحْيِهِ عَلَى الْإِسْلَامِ , وَمَنْ تَوَفَّيْته مِنَّا فَتَوَفَّهُ عَلَى الْإِيمَانِ

"O Allah! Forgive our living and dead, present and absent, big and small, men and women. O Allah! Whoever among us is kept alive by You, keep him alive on Islam, and whoever You give death, let him die on Imaan."

اللَّهُمَّ اغْفِرْ لَهُ وَارْحَمْهُ وَعَافِهِ وَاعْفُ عَنْهُ , وَأَكْرِمْ نُزُلَهُ وَوَسِّعْ مُدْخَلَهُ وَاغْسِلْهُ بِالْمَاءِ وَالثَّلْجِ وَالْبَرَدِ وَنَقِّهِ مِنْ الْخَطَايَا كَمَا يُنَقَّى الثَّوْبُ الْأَبْيَضُ مِنْ الدَّنَسِ , وَأَبْدِلْهُ دَارًا خَيْرًا مِنْ دَارِهِ وَأَهْلًا خَيْرًا مِنْ أَهْلِهِ وَزَوْجًا خَيْرًا مِنْ زَوْجِهِ , وَأَدْخِلْهُ الْجَنَّةَ وَأَعِذْهُ مِنْ عَذَابِ الْقَبْرِ وَعَذَابِ النَّارِ

It is better if both these duas are recited. Apart from these two, other duas have also been related in the hadith. One could therefore choose whichever dua one wishes.

Once this dua has been recited, Allahu Akbar should be said once more. After this takbeer make duaa to the dead, yourself, and all the Muslims. Then salaam should be made just as it is made for any other prayer.
