Answer: Yes, they can. It is not permissible for women to visit any blessed tomb other than that of our Holy Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم. Visiting this sacred tomb is a grand and auspicious Sunnaĥ and is almost Wājib. The Holy Quran has declared it a glorious means of the forgiveness of sins. The 64th verse of Sūraĥ An-Nisā (part 5) states:
وَ لَوۡ اَ نَّہُمۡ اِذۡ ظَّلَمُوۡۤ ا اَنۡفُسَہُمۡ جَآءُ وۡ کَ فَاسۡتَغۡفَرُ وا اللّٰہَ وَ اسۡتَغۡفَرَ لَہُمُ الرَّسُوۡلُ لَوَ جَدُ و ا اللّٰہَ تَوَّ ا بًا رَّحِیۡمًا ﴿۶۴﴾
And if when they do injustice to their souls, then O Beloved! They should come to you and then beg forgiveness of Allah and the Prophet should intercede for them, then surely, they will find Allah the Most Relenting, the Merciful.
[Kanz-ul-Īmān (Translation of Quran)] (Part 5, Sūraĥ An-Nisā, verse 64)
A sacred Ḥadīš states; ‘If anyone visits my grave, then my intercession shall become incumbent for him.’ (Dār Quṭnī, vol. 2, pp. 351, Ḥadīš 2669)
Sayyidunā Abū Ĥurayraĥ رَضِىَ اللهُ تَعَالٰی عَـنْهُ reports the following Ḥadīš of the Noblest Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم, ‘Whoever performed Hajj but did not visit me has oppressed me.’
(Al-Kāmil-fī-Ḍu’afā-ir-Rijāl, vol. 8, pp. 248)
So we learn that firstly, visiting the blessed tomb of the Holy Prophet صَلَّى الـلّٰـهُ تَـعَـالٰى عَـلَيْـهِ وَاٰلـِهٖ وَسَـلَّم is incumbent [close to Wājib], secondly, it is a means for the acceptance of repentance, thirdly, it is a way to earn his intercession and fourthly, it saves you from oppressing the Holy Prophet صَلَّى الـلّٰـهُ تَـعَـالٰى عَـلَيْـهِ وَاٰلـِهٖ وَسَـلَّم. All these factors have made it necessary for all of the Blessed Prophet’s slaves and maids to kiss the soil of his glorious court, contrary to other graves and tombs,
