Hajj & Umrah

Travelling without a mahram

Q: I am living in Riyadh. I want to go for umrah from Riyadh. My brother is in Makkah and my sister is in Jeddah. Can I travel for umrah with my children by flight from Riyadh to Jeddah and perform umrah with my brother? He will pick me up from the  airport. If I stay for three to four days in Jeddah, from their can I perform umrah? From where must make the intention of Ihraam?

Hajj with Haraam money

Q: Is a hajj that is performed by someone who's money is 100% haraam from selling drugs accepted, the person is a drug dealer. When the person is on Arafat is all his sins also forgiven when returning as a Hajji. Please give a detial explanation & what is the punishment.

Riyaadul Jannah

Q: It was narrated from Abu Hurayrah that Muhammad (Sallallahu Alayhi Wasallam) said: "The area between my house and my minbar is one of the gardens (rawdah) of Paradise, and my minbar is on my cistern (hawd).

My question is that that will that part of earth be raised into jannah its a duplicate of that part of earth?

Also I heard its shirk to dua from other poeple I mean like you trust into them. Or making dua though someone. Please shed some light on this topic with the opinion of the hanafi maddhab.
