And those who came after them say, “O our Lord! Forgive us, and our brothers who accepted faith before us, and do not keep any malice in our hearts towards the believers – O our Lord! Indeed You only are the Most Compassionate, Most Merciful.”. (Hashr 59:10)
Note that the above verse is a very strong evidence of the practice of the Sahaba (may Allah be well pleased with them), which was so loved by Allah that it is part of the Holy Quran. Why would the Sahaba (may Allah be well pleased with them) pray for the deceased people if their prayer was of no benefit ?? And to top it all, Allah the Almighty has approved and praised their action !!
“O our Lord! And forgive me, and my parents, and all the Muslims on the day when the account will be established.” (Ibrahim 14:41)
The benefit of the above verse is obvious. The prayer of Prophet Syedna Ibrahim (peace be upon him), includes all believers – right from the beginning i.e. those before him, and till the end of this world i.e. even those who are not yet born. Al Hamdo Lillah !! And this prayer is often made in the last part (Qaadah) of our Salaat.
“And those who believe and whose families follow them in Faith, — to them We shall join their families: nor shall We deprive them of the fruit of anything of their works: yet each individual is in pledge for his deeds.” (Toor 52:21)
This verse says that children will be admitted into Paradise because of the righteousness of the parents.
“And lower your wing humbly for them, with mercy, and pray, “My Lord! Have mercy on them both, the way they nursed me when I was young.” (Bani Israel 17:24)
This verse is in fact a command from Allah for all believers to seek mercy for their parents. So what is your opinion ?? Will not the command of Allah hold any benefit for the deceased parent ?? It certainly does.
Also note that there are several other verses from the Holy Quran that teach us to pray, and the prayer includes all Muslim brothers & sisters (living, passed away or yet to be borne).
Readers are requested to reflect on the fact that the above verses are part of the Holy Quran – they are read perhaps millions of times every day all over the world, as part of regular recitation, and also as Qirat within Salaat, and also as prayer in the last part (Qaadah) of Salaat.
