Dua for death
Allahhum maghfirlahu warhamhu wa’fu ‘anhu wa ‘afihee wa-akrim nuzuluhu wa was-si’ mudkhalahu, waghsilhu bil maee wath thalji wal bardi, wa naq-qihi minal ‘khataya Kama yunaq- qath thawbul abyadu minad danasi, wa abdilhu daran Khayram min darihi, wa ahlan Khayram min ahlihi wa zawjan khayrum min-zawjihi, wa adkhil hul jan-nata, waqihi fitnatal qabri wa ‘Azaban nar
O Allah! Forgive him and have Mercy on him and give him strength and pardon him. Be generous to him and cause his entrace to be wide and wash him with water and snow and hail.
Cleanse him of his transgressions as white cloth is cleansed of stains. Give him an abode better than his home, and a family better than his family and a wife better than his wife. Take him into Paradise and protect him from the punishment of the grave (and of the fire)
Allahum maghfir lihayyina, wa mayyitinaa, wa shaahidina, wa ghaa-’ibina, wa sagheerina, wa kabeerina, wa dhakarrina wa untha. Allahumma man ahyaitahu mina fa ahyihi ‘alal Islami wa man tawaf-faytahu mina fatawaffahu ‘alal imani. Allahumma la tahrima arjahu wa la tudhillana ba’dahu
O Allah! Forgive our living and our dead, those who are with us and those who are absent, our young and our old, our men and our women. O Allah! Whomever you keep alive from us keep him alive on Islam, and whomever you take away from us, take him as a believer. O Allah! Do not leave us bereft of his good and do not send us astray after them.
[Ibn Majah 1:480, Ahmad 2:368]
Allahumma inna [name the person] fi dhimmatika, wa habli jiwaarika, faqihi min fitnaltil qabri, qa adhaban-naari, wa anta ahlul Wafaa’i wal-Haqqi. Faghfir lahu warhamhu. Innaka antal Ghafurur-Raheem
O Allah! Surely [name the person] is under Your protection, and in the rope of Your security, so save him from the trial of the grave and from the punishment of the Fire. You fulfill promises and grant rights, so forgive him and have mercy on him. Surely You are Most Forgiving, Most Merciful.
[Ibn Majah, abu Dawud 3:211]
Allahumma abduka wabnu amtika ahtaaja ila rahmatika wa anta Ghaniyyun an ‘adhaabihi in kaana muhsinan fazid fi hasanatihi, wa in kaana musii’an fata-jaawaz ‘anhu
O Allah! Your slave, the child of Your slave is in need of Your mercy, and You are not in need of his torment. If he was pious then increase his rewards, and if he was a transgressor then pardon him.
[Al-Hakim 1:359 who graded it authentic and ath-Thahabi agreed with him]
