“I heard the Messenger of Allah ﷺ say: ‘When you offer the prayer for the deceased, supplicate sincerely for him.’”  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا صَلَّيْتُمْ عَلَى الْمَيِّتِ فَأَخْلِصُوا لَهُ الدُّعَاءَ  

“When the Messenger of Allah ﷺ offered the funeral prayer he would say: ‘Allahummaghfir lihayyina wa mayyitina, wa shahidina wa gha’ibina, wa saghirina wa kabirina, wa dhakarina wa unthana. Allahumma man ahyaitahu minna fa'ahyihi ‘alal-Islam, wa man tawaffaytahu minna fa tawaffahu ‘alal- iman. Allahumma la tahrimna ajrahu wa la tudillana ba’dah. [O Allah, forgive our living and our dead, those who are present and those who are absent, our young and our old, our males and our females. O Allah, whomever of us You cause to live, let him live in Islam, and whomever of us You cause to die, let him die in (a state of) faith. O Allah, do not deprive us of his reward, and do not let us go astray after him].’”  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا صَلَّى عَلَى جِنَازَةٍ يَقُولُ اللَّهُمَّ اغْفِرْ لِحَيِّنَا وَمَيِّتِنَا وَشَاهِدِنَا وَغَائِبِنَا وَصَغِيرِنَا وَكَبِيرِنَا وَذَكَرِنَا وَأُنْثَانَا اللَّهُمَّ مَنْ أَحْيَيْتَهُ مِنَّا فَأَحْيِهِ عَلَى الإِسْلاَمِ وَمَنْ تَوَفَّيْتَهُ مِنَّا فَتَوَفَّهُ عَلَى الإِيمَانِ اللَّهُمَّ لاَ تَحْرِمْنَا أَجْرَهُ وَلاَ تُضِلَّنَا بَعْدَهُ  

“The Messenger of Allah ﷺ offered the funeral prayer for a man among the Muslims and I heard him say: ‘O Allah, so-and-so the son of so-and-so is in Your case and under Your protection. Protect him from the trial of the grave and the torment of the Fire, for You are the One Who keeps the promise and You are the Truth. Forgive him and have mercy on him, for You are the Oft-Forgiving, Most Merciful.”  

صَلَّى رَسُولُ اللَّهِ ﷺ عَلَى رَجُلٍ مِنَ الْمُسْلِمِينَ فَأَسْمَعُهُ يَقُولُ اللَّهُمَّ إِنَّ فُلاَنَ بْنَ فُلاَنٍ فِي ذِمَّتِكَ وَحَبْلِ جِوَارِكَ فَقِهِ مِنْ فِتْنَةِ الْقَبْرِ وَعَذَابِ النَّارِ وَأَنْتَ أَهْلُ الْوَفَاءِ وَالْحَقِّ فَاغْفِرْ لَهُ وَارْحَمْهُ إِنَّكَ أَنْتَ الْغَفُورُ الرَّحِيمُ  

“I saw the Messenger of Allah ﷺ offering the funeral prayer for a man among the Ansar, and I heard him say: ‘Allahumma salli ‘alayhi waghfirlahu warhamhu, wa ‘afihi wa’fu ‘anhu, waghsilhu bi ma’in wa thaljin wa baradin, wa naqqihi min adh-dhunubi wal-khataya kama yunaqqath-thawbul-abyadu minad-danas, wa abdilhu bi darihi daran khayran min darihi, wa ahlan khayran min ahlili, wa qihi fitnatal-qabri wa ‘adhaban-nar. (O Allah, send blessing upon him, forgive him, have mercy on him, keep him safe and sound, and pardon him; wash him with water and snow and hail, and cleanse him of sins just as a white garment is cleansed of dirt. Give him in exchange for his house that is better than his house, and a family that is better than his family. Protect him from the trial of the grave and the torment of the Fire).’”  

شَهِدْتُ رَسُولَ اللَّهِ ﷺ صَلَّى عَلَى رَجُلٍ مِنَ الأَنْصَارِ فَسَمِعْتُهُ يَقُولُ اللَّهُمَّ صَلِّ عَلَيْهِ وَاغْفِرْ لَهُ وَارْحَمْهُ وَعَافِهِ وَاعْفُ عَنْهُ وَاغْسِلْهُ بِمَاءٍ وَثَلْجٍ وَبَرَدٍ وَنَقِّهِ مِنَ الذُّنُوبِ وَالْخَطَايَا كَمَا يُنَقَّى الثَّوْبُ الأَبْيَضُ مِنَ الدَّنَسِ وَأَبْدِلْهُ بِدَارِهِ دَارًا خَيْرًا مِنْ دَارِهِ وَأَهْلاً خَيْرًا مِنْ أَهْلِهِ وَقِهِ فِتْنَةَ الْقَبْرِ وَعَذَابَ النَّارِ قَالَ عَوْفٌ فَلَقَدْ رَأَيْتُنِي فِي مُقَامِي ذَلِكَ أَتَمَنَّى أَنْ أَكُونَ مَكَانَ ذَلِكَ الرَّجُلِ  

“The Messenger of Allah ﷺ, Abu Bakr and ‘Umar did not give us so much leeway in anything as they did with regard to the prayer for the deceased,” meaning that there was nothing affixed.  

مَا أَبَاحَ لَنَا رَسُولُ اللَّهِ ﷺ وَلاَ أَبُو بَكْرٍ وَلاَ عُمَرُ فِي شَىْءٍ مَا أَبَاحُوا فِي الصَّلاَةِ عَلَى الْمَيِّتِ يَعْنِي لَمْ يُوَقِّتْ
