Sincere tawbah

Q: I have a friend who entered an unlawful relationship about 7 months ago. She ended the relationship after two months due to the guilt. She feels very impure and cries a lot about her sin. She claims to believe in Allah's forgiveness, but is unable to bear herself. She breaks down a lot and feels like she is no longer a good and pure woman. She also feels like it is wrong to put it behind her. Is it possible that Allah has wiped away her sin and purified her?

Method of giving up watching TV

Q: My parents have always guided me away from certain sins and I would say that they are Islamically inclined in that they read all salaahs, abundant Quran and stay away from most sins. However, the one habit I've noticed that they seem unable to give up is their addiction to watching television. They watch Indian soapies and Hollywood/Bollywood movies till late at night. Sometimes I think they fall asleep with their TV switched on. Sometimes they will be watching a funny video or an interesting movie while I am getting something from their room and they'd tell me to come and sit down and watch with them. I have just recently begun cutting tv out of my life and as much as I want to watch as well, I feel guilty while doing so. What dua can I read so that my parents will stop watching TV and will get more hidayat? And what can I read to strengthen my willpower so that I will not get tempted to watch TV or commit any other sins?

Uneven haircut

Q: I am a boy. When I go to the barber shop, I ask him to cut my hair short on my sides and the back of my head. But I ask him to keep the front hairs relatively bigger than those at the back. Is it permissible or must all the hairs be cut equal from all sides?

Inheritance

Q: If a man passes away leaving behind his wife as his only inheritor, how would the inheritance be distributed? Would it make a difference if he also had a maternal aunt (mother's sister)?

Authentication of a Hadith

Q: Kindly inform me if the following is authentic : In a Hadith Qudsi, Allah Almighty says: O son of Adam, do not fear those who have authority over you as long as My authority is enduring, and My authority never runs out. O son of Adam, do not be afraid of a tight livelihood when My treasuries are full and My treasuries never run out. O son of Adam, do not ask anybody else except Me and I am yours, and when you ask Me you find Me; but if you ignore Me, I will turn away from you, and you will miss the whole good. O son of Adam, I have created you to worship Me, not to play, and I ensured your sustenance so that you do not torment yourself (by worrying about it — let the physical parts of your body work but your heart and mind be in peace by putting your trust in God). I swear in My Power and Might, if you’re satisfied with what I apportioned for you, I will give your mind and body peace, but if you will not be satisfied with what I apportioned for you, I swear in My Power and Might, I will make you run after the world like the beasts run in the wild, then you will have nothing except what I had apportioned to you, and you have been disgraced. O son of Adam, the creation of the seven heavens and the earth did not fatigue Me, will passing you a loaf of bread cause Me to tire. O son of Adam, I did not forget whoever disobeys Me; how will I forget whoever obeys Me, and I am a Merciful Lord, and I have power over all things? O son of Adam, do not ask Me the sustenance of tomorrow as I did not ask you the work of tomorrow. O son of Adam, I love you so it is My Right that you love Me.
