541. hadíth
وَقَالَ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ: «مَا مِنْ عَبْدٍ مُؤْمِنٍ زَارَ قَبْرَ مُؤْمِنٍ فَقَرَأَ عِنْدَهُ « إِنّٰا أَنْزَلْنٰاهُ فِي لَيْلَةِ اَلْقَدْرِ » سَبْعَ مَرَّاتٍ إِلاَّ غَفَرَ اَللَّهُ لَهُ وَ لِصَاحِبِ اَلْقَبْرِ.
Imam Ali ibn Musa Ar-Ridha (a.s) said: "Whenever a believing servant visits the grave of a believer and recites 'Indeed, We revealed it [the Qur'an] on the Night of Qadr' Surah Al-Qadr (97:1-5) seven times, Allah (swt) will forgive him and the person buried in the grave”.
