Can i be mahrm to my sister who i am atracted to?

bro it is not permissible for you to get sexually attracted to your sister..u have a blood-relation with her and islam doesnt permits getting into sexual attraction with sisters(I m only mentioning sisters as ur question is prior to sister)....U should stop thinking about all this, coz if u open it up to your sister, may be she would'nt like to talk to u further more and maybe her trust upon you would be broken...moreover if u feel that u are not able to control yourself then tell other mahram of your family to travel with her in her journey..!! and please dont think to commit adultery with your sister as mahram's are there to guard there sisters and not getting sexually attracted to them..!! SEEK ALLAH'S guidance and FEAR him..!

IN SURAH NISA, ALLAH(swt)ORDERS MEN:

"And marry not women whom your fathers married, except what has already passed; indeed it was shameful and most hateful, and an evil way. Forbidden to you (for marriage) are: your mothers, your daughters, your sisters, your brother's daughters, your sister's daughters, your foster mother who breastfed you, your foster sisters, your wives' mothers, your stepdaughters under your guardianship, born of your wives to whom you have gone in -but there is no sin on you if you have not done so (to marry their daughters), the wives of your sons who spring from your loins, and two sisters in wedlock at the same time, except for what has already passed; verily Allah is Oft-Forgiving, Most Merciful. " [4:22-23]

"Nor come nigh to adultery: for it is a shameful (deed) and an evil, opening the road (to other evils)." (Al-Isra' 17: 32)

"Those who guard their sexual organs except with their spouses or those whom their right hands possess, for (with regard to them) they are without blame.But those who crave something beyond that are transgressors." (Al-Mu'minoon 23:5-7)

These are the objectives of sex mentioned by Allah in the verse that reads:

"...come not nigh to indecent deeds. Whether open or secret..." (Al-Annam 6:151)

"Nor come nigh to adultery: for it is a shameful (deed) and an evil, opening the road (to other evils)." (Al-Isra' 17: 32)

"Say: the things that my Lord hath indeed forbidden are: Indecent deeds, whether open or secret; sins and trespasses against truth or reason; assigning of partners to Allah, for which He hath given no authority; and saying things about Allah of which ye have no knowledge." (Al-Araf 7:33)

Also we must always keep in mind the verses of the following type:

"And fear the Day when ye shall be brought back to God. Then shall every soul be paid what it earned, and none shall be dealt with unjustly." (Al-Baqqarah 2:281)

Allah(swt) says: "God accepts the repentance of those who do evil in ignorance and repent soon afterwards; to them will God turn in mercy: For God is full of knowledge and wisdom. (17) Of no effect is the repentance of those who continue to do evil, until death faces one of them, and he says, "Now have I repented indeed;" nor of those who die rejecting Faith: for them have We prepared a punishment most grievous." (An-Nissa 4:17-18) Also,

"And establish regular prayers at the two ends of the day and at the approaches of the night: For those things, that are good remove those that are evil: Be that the word of remembrance to those who remember (their Lord)" (Hüd 11:114)

U cant be Mahram then.

Amuslim female can't travel with out a mahram even she can't go to hajj with out amahram. A mahram to any female must fullfil this qualification 1.it should be impossible for him to marry her through out her life. 2.islam made this{the mahram}to protect the female frm any haram action that could be done to her by other strangers in her journey so if her mahram afraid that he could do something wrong to her he can't be mahram to her becouse islam made mahram fear of fitna. So if ali don't afraid to tell her that u fear fitna and let u not to involve any action that can lead u to disobey Allah and follow satan's thorny path. Or you can find any other justification that will not damage her mind and your family. Or u just tell your sister in private that u can't follow her becouse of this and this and pursuid her the reality that we r running from jahanama{the hell} or u can ask a islamic scholar to present u the reasons why islam made mahram and explain to her that u can't be mahram to her. Or let some else follow her who is mahram to her like her father,mother or any one of ur siblings.

Jazakallah brother,may allah protect you from fornicatiom
