It was narrated from ‘Aishah that the Messenger of Allah ﷺ gave permission for visiting the graves.  

ابن ماجة:١٥٧٠حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعِيدٍ الْجَوْهَرِيُّ حَدَّثَنَا رَوْحٌ حَدَّثَنَا بِسْطَامُ بْنُ مُسْلِمٍ قَالَ سَمِعْتُ أَبَا التَّيَّاحِ قَالَ سَمِعْتُ ابْنَ أَبِي مُلَيْكَةَ عَنْ عَائِشَةَ

أَنَّ رَسُولَ اللَّهِ ﷺ رَخَّصَ فِي زِيَارَةِ الْقُبُورِ
