The prophet (ﷺ) asked his Lord for permission to visit the grave of his mother
حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَمُحَمَّدُ بْنُ عَبَّادٍ، - وَاللَّفْظُ لِيَحْيَى - قَالاَ حَدَّثَنَا مَرْوَانُ، بْنُ مُعَاوِيَةَ عَنْ يَزِيدَ، - يَعْنِي ابْنَ كَيْسَانَ - عَنْ أَبِي حَازِمٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " اسْتَأْذَنْتُ رَبِّي أَنْ أَسْتَغْفِرَ لأُمِّي فَلَمْ يَأْذَنْ لِي وَاسْتَأْذَنْتُهُ أَنْ أَزُورَ قَبْرَهَا فَأَذِنَ لِي " .
Abu Huraira reported Allah's Messenger, (ﷺ) as saying: I sought permission to beg forgiveness for my mother, but He did not grant it to me. I sought permission from Him to visit her grave, and He granted it (permission) to me.
