“The Prophet ﷺ visited the grave of his mother and wept, causing the people around him to weep. Then he said: ‘I asked my Lord for permission to seek forgiveness for her, but He did not give me permission. Then I asked my Lord for permission to visit her grave and He gave me permission. So visit the graves, for they will remind you of death.’” (Using translation from Ibn Mājah 1572)  

زَارَ رَسُولُ اللهِ ﷺ قَبْرَ أُمِّهِ فَبَكَى وَأَبْكَى مَنْ حَوْلَهُ وَقَالَ «اسْتَأْذَنْتُ رَبِّي فِي أَنْ أَسْتَغْفِرَ لَهَا فَلَمْ يُأْذَنْ لِي وَاسْتَأْذَنْتُهُ فِي أَنْ أَزُورَ قَبْرَهَا فَأَذِنَ لِي فَزُورُوا الْقُبُورَ فَإِنَّهَا تُذَكِّرُ الْمَوْتَ»
