اَلسَّلَامُ عَلَيْكُمْ دَارَ قَوْمٍ مُؤْمِنِيْنَ وَأَتَاكُمْ مَا تُوعَدُونَ غَدًا مُؤَجَّلُونَ وَإِنَّا إِنْ شَاءَ اللَّهُ بِكُمْ لَاحِقُونَ اَللَّهُمَّ اغْفِرْ لِأَهْلِ بَقِيعِ الْغَرْقَدِ

As-salamu 'alaikum da-ra kaumin mu’minin, wa ata-kum ma-tu’aadun ‘gadan muajjalun, wa inna-insha- allahu bikum la-’hikun. Alla-humma’gfir liahli baki‘eil garqad.

Peace be upon you, O you who believers inhabitants of the grave! The promise that was given to you has come to you, and you are waiting for the day to come. And we will meet you by the will of Allah. O Allah, forgive the inhabitants of the Baqi graveyard. Ayesha (RA) said, "When Rasoolullah (ﷺ) stayed in my house, he used to go to the Baqi' graveyard at the last hour of night and say these words.
