Tirmidhi

Benefits and Issues:
This prohibition is abrogated:
Visiting graves was prohibited for both men and women, but later this prohibition was abrogated and permission was granted to all. This hadith is from the period when visiting graves was prohibited.
Imam Hakim rahimahullah says regarding this and similar ahadith:
“The ahadith narrated about the prohibition of visiting graves are abrogated.” [المستدرك على الصحيحين : 1385]
↰ The statement of Imam Hakim rahimahullah is absolutely correct; the following evidences also support this position.

Evidence Number: ➊
Abdullah bin Abu Mulaykah, the Tabi‘i (Successor), rahimahullah, narrates:
Sayyidah Aisha radi Allahu anha once came from the direction of the graveyard, so I asked her: Mother of the Believers! Where have you come from? She replied: From the grave of my brother Abdur Rahman bin Abu Bakr radi Allahu anhuma. I said: Did not the Messenger of Allah sallallahu alayhi wa sallam prohibit visiting graves? Sayyidah radi Allahu anha replied: Yes, he did prohibit it, but later he commanded visiting graves.” [المستدرك على الصحيحين للحاكم: 376/1، السنن الكبريٰ للبيهقي 78/3 وسنده صحيح]
◈ Hafiz Dhahabi rahimahullah declared this hadith “sahih (authentic).” [تلخيص المستدرك : 376/1]
◈ Hafiz Iraqi rahimahullah called its chain “good (jayyid).” [تخريج احاديث الاحياء : 2608/8]
◈ Hafiz Busiri writes: “This chain is authentic and its narrators are trustworthy.” [مسباح الزجاجة : 568]
The wording in Sunan Ibn Majah [1570] is as follows:
«رخص فى زيارة القبور»
“Then the Messenger of Allah sallallahu alayhi wa sallam permitted visiting graves.”

Evidence Number: ➋
Sayyiduna Buraydah Aslami radi Allahu anhu narrates that the Messenger of Allah sallallahu alayhi wa sallam said:
«نهيتكم عن زيارة القبور، فزوروها»
“I had forbidden you from visiting graves, but now you may visit the graveyards.” [صحيح مسلم : 977]
↰ This noble hadith is general, which includes both men and women. The aforementioned hadith also indicates this.

Benefit:
This refers to women who visit (the graves) repeatedly.
"Zawwarat" is an intensive form, meaning women who visit frequently or repeatedly.
The permissibility of visiting occasionally is understood from this hadith.
When Aisha (radi Allahu anha) asked the Messenger of Allah (sallallahu alayhi wa sallam) how she should supplicate for those buried when visiting the graveyard, the Messenger of Allah (sallallahu alayhi wa sallam) did not say to her, "Do not go at all."
Rather, he said: (As-salamu ‘ala ahli ad-diyari min al-mu’minina wal-muslimin... etc.)
See:
(Sahih Muslim, Al-Jana’iz, Chapter: What is to be said upon entering the graves and supplicating for their inhabitants:
Hadith: 974)
