أَعْظَمَ اللَّهُ أَجْرَكَ، وَأَحْسَنَ عَزَاءَكَ، وَغَفَرَ لِمَيِّتِكَ، إِنَّ لِلَّهِ مَا أَخَذَ وَلَهُ مَا أَعْطَى، وَكُلُّ شَيْءٍ عِنْدَهُ بِأَجَلٍ مُسَمًّى
A'dzamallahu ajraka, wa-ahsana 'azaa-ak, waghafara limayyitika. Inna lillahi maa akhadza wa lahuu maa a'thaa wakulla syai-in 'indahuu bi-ajalin musammaa
May Allah magnify your reward, grant you a beautiful consolation and forgive your deceased. Indeed, to Allah belongs what He has taken and to Him belongs what He has given, and everything with Him has an appointed term.
