[Machine] That Fatimah, the daughter of the Prophet (Peace be upon him), used to visit the grave of her uncle Hamza every Friday and pray and cry by it. This hadith is narrated by trustworthy narrators, and I have thoroughly researched the encouragement to visit graves in order to participate in promoting its virtues and for the sinner to know his own shortcomings. It is a recommended practice. May Allah bless Muhammad and his family.  

أَنَّ فَاطِمَةَ بِنْتَ النَّبِيِّ ﷺ كَانَتْ «تَزُورُ قَبْرَ عَمِّهَا حَمْزَةَ كُلَّ جُمُعَةٍ فَتُصَلِّي وَتَبْكِي عِنْدَهُ» هَذَا الْحَدِيثُ رُوَاتُهُ عَنْ آخِرِهِمْ ثِقَاتٌ وَقَدِ اسْتَقْصَيْتُ فِي الْحَثِّ عَلَى زِيَارَةِ الْقُبُورِ تَحَرِّيًا لِلْمُشَارَكَةِ فِي التَّرْغِيبِ وَلِيَعْلَمَ الشَّحِيحُ بِذَنَبِهِ أَنَّهَا سُنَّةٌ مَسْنُونَةٌ وَصَلَّى اللَّهُ عَلَى مُحَمَّدٍ وَآلِهِ أَجْمَعِينَ
