Marital issues

Q: I need help. I'm a mother of three kids and my husband is in another country. It's been two months he is not replying to my emails or my
phone calls. I have called him 100 times with more than 100 emails. I need your help give me a dua so he can call me and talk to me because he is with friends who is making him do drugs and drink alcohol and telling him not go call me. I am married to him I am under his nikaah and he's neglecting me and my kids for his friends. He is not even supporting me with money. My father is helping me to pay my rent and utilities bills. Give me a dua so my husband can come back to me Insha Allah and listen to me and love me like he used to. Please send me a dua urgently it's been 2 months he didn't call or talk to me or his kids. When I call him he ignores my calls all his friends pick up his phone and tells me not to call him again. I am lost what to do my kids are crying and sick after the fathers voice when I email him that your kids are sick he used to say show me proof. That's all he would say and curse me blaming men on me. I need a dua urgently please. 

Eating and drinking Haraam

Q:

  1. Is there a hadith which says a person who eats or drinks haram, his dua and salah is not accepted for 40 days?
  2. After eating haram, if the person repents straight away will his dua and salah be accepted or it will still not be accepted until after 40 days?

Hadith Query

Q: I have seen this in posts but without any reference. Is it possible to get the exact text and where its from?

Jibrail (alaihissalam) once came to The Holy Prophet (Sallallahooalahi-Wasallam) and said Allah has given me the knowledge to count every leaf on earth,every fish in the sea, every star in the sky and every particle of sand on earth, but there's only one thing I cant count. Prophet (Sallallahu Alayhi Wasallam) asked Jibrail (Alayhis Salaam) what is it? Jibrail (Alayhis Salaam) replied: When one of your Ummah recites Durood or salaams to you the blessing Allah showers upon him becomes impossible for me to count.

How should one explain to one's mother that what she is involved in is wrong?

Q: My mother is 60+ and everyday she sits on her laptop and phone chatting to various men/boys (some of them old enough to be her sons) although this does not interfere with her namaaz I still believe this is wrong! When I confront her about it, she get so upset and throws my mistakes in my face. She is on all the dating sites and chats to various men from around the globe! Please help! How can I make her undrstand that what she is doing is a sin as she doesn't see it that way?
