If u’re going to read Fatiha for them it’s alright.. but to ask them to help deliver u’re dua’s.. isn’t right.
Those people who reject the idea altogether quote the following hadith in which the Prophet (peace and blessings be upon him) is reported to have said: ‘Allah has cursed women who often go and visit graves.’ Another hadith relates an incident in which the Prophet (peace and blessings be upon him) asked his daughter, Fatimah, why she had left her house. She is reported to have replied: ‘I went to the family of such-and-such a dead person and I prayed to Allah to shower His mercy on the person.’ The Prophet (peace and blessings be upon him) is then reported to have asked whether she went to the funeral and she replied: ‘God forbid, how could I do such a thing when I have heard that you have forbidden this?’
However, those looking for evidence to show that women are allowed to visit graves quote some of the following ahadith: According to one tradition, the Prophet (peace and blessings be upon him) is reported – after acknowledging that he had earlier forbade women to visit cemeteries – to have said: ‘Now you are allowed to go and visit them, for they remind you of the life to come.’ In another hadith, reported by Muslim and Al-Bukhari, the Prophet (peace and blessings be upon him) is reported by Umm Atiyyah to have forbade women from following funeral prayers –‘… but Umm Atiyyah added, ‘he did not stress it.’
