Taking a false oath

Q: I smoked weed once or twice which I am not sure is haraam or not. Anyways recently my mother found it out from my bag. It wasn't mine and she made me swear upon her head and the quran that I haven't ever smoked weed in my life and I did. Please tell me did I do wrong by taking a false oath and what penalty I have to pay for forgiveness? If I hadn't done it, she might be heartbroken.

Did Abu Talib accept Islam?

Q: Why is there a lot of ikhtilaaf on the Imaan of Hazrat Abu Talib? Some say he is Kafir, some say Sahaabi and some say to keep queit about Hazrat Abu Talib?

My Question is that if a person like me who does not have much knowladge about Islam, by talking about Hazrat Abu Talib, will my Iman be snatched away? Is this a part of basic Aqeeda or Belief? Please Explain?

Linking oneself to a pious person

Q: I am a 21 year old from the US. I have committed so much wrong in these past couple of years and feel lost in this world without Allah because I’ve tried living both ways but subhanallah no matter how hard I try to stick to the sunnah I go back to my wrong doing. I cry almost every night to the point where I’m asking Allah if I’m being tested or punished. I ask for His help every night and cry and beg Him to keep me away and I know that Allah knows best. I know He’s the only one that can help me. I know that no one knows me better than He does and I want to be close to Him again. I want my life and heart and mind filled with noor and iman.
