The "concept of Intercession" exists in Islam and ALL muslims should be aware of it - plain and simple...
In Al-Quran Allah Almighty addresses humanity and says:
Chapter 2 Verse 255
Allah! there is no Allah but He the living the Self-subsisting Eternal. No slumber can seize him nor sleep. His are all things in the heavens and on earth.
Who is there can intercede in His presence except as He permitteth? He knoweth what (appeareth to his creatures as) before or after or behind them. Nor shall they compass aught of his knowledge except as He willeth. His throne doth extend over the heavens and the earth and He feeleth no fatigue in guarding and preserving them. For He is the Most High the Supreme (in glory).
========================================
Therefore indeed there will be permission from Allah swt himself to many of his servants to intervene for others. One of these servants of allah swt is Prophet Mohammed (sal Allaahu alayhi waSalam) who shall be granted the right to intercede with Allah swt's permission:
Sahih Al-Bukhari Hadith 9.507 Narrated by Anas (may Allaah be pleased with him)
The Prophet (peace be upon him) said, "Allah will gather the believers on the Day of Resurrection in the same way (as they are gathered in this life), and they will say, 'Let us ask someone to intercede for us with our Lord that He may relieve us from this place of ours.' Then they will go to Adam and say, 'O Adam! Don't you see the people (people's condition)? Allah created you with His Own Hands and ordered His angels to prostrate before you, and taught you the names of all the things. Please intercede for us with our Lord so that He may relieve us from this place of ours.' Adam will say, 'I am not fit for this undertaking' and mention to them the mistakes he had committed, and add, "But you'd better go to Noah as he was the first Apostle sent by Allah to the people of the Earth.' They will go to Noah who will reply, 'I am not fit for this undertaking,' and mention the mistake which he made, and add, 'But you'd better go to Abraham, Khalil Ar-Rahman.'
They will go to Abraham who will reply, 'I am not fit for this undertaking,' and mention to them the mistakes he made, and add, 'But you'd better go to Moses, a slave whom Allah gave the Torah and to whom He spoke directly.' They will go to Moses who will reply, 'I am not fit for this undertaking,' and mention to them the mistakes he made, and add, 'You'd better go to Jesus, Allah's slave and His Apostle and His Word (Be: And it was) and a soul created by Him.' They will go to Jesus who will say, 'I am not fit for this undertaking, but you'd better go to Muhammad whose sins of the past and the future had been forgiven (by Allah).' So they will come to me and I will ask the permission of my Lord, and I will be permitted (to present myself) before Him. When I see my Lord, I will fall down in (prostration) before Him and He will leave me (in prostration) as long as He wishes, and then it will be said to me, 'O Muhammad! Raise your head and speak, for you will be listened to; and ask, for you will be granted (your request); and intercede, for your intercession will be accepted.' I will then raise my head and praise my Lord with certain praises which He has taught me, and then I will intercede. Allah will allow me to intercede (for a certain kind of people) and will fix a limit whom I will admit into Paradise.
I will come back again, and when I see my Lord (again), I will fall down in prostration before Him, and He will leave me (in prostration) as long as He wishes, and then He will say, 'O Muhammad! Raise your head and speak, for you will be listened to; and ask, for you will be granted (your request); and intercede, for your intercession will be accepted.' I will then praise my Lord with certain praises which He has taught me, and then I will intercede. Allah will allow me to intercede (for a certain kind of people) and will fix a limit to whom I will admit into Paradise, I will return again, and when I see my Lord, I will fall down (in prostration) and He will leave me (in prostration) as long as He wishes, and then He will say, 'O Muhammad! Raise your head and speak, for you will be listened to, and ask, for you will be granted (your request); and intercede, for your intercession will be accepted.' I will then praise my Lord with certain praises which He has taught me, and then I will intercede. Allah will allow me to intercede (for a certain kind of people) and will fix a limit to whom I will admit into Paradise. I will come back and say, 'O my Lord! None remains in Hell (Fire) but those whom Qur'an has imprisoned therein and for whom eternity in Hell (Fire) has become inevitable.' "
The Prophet (peace be upon him) added, "There will come out of Hell (Fire) everyone who says: 'La ilaha illal-lah (there is none worthy of worship except Allaah),' and has in his heart good equal to the weight of a barley grain. Then there will come out of Hell (Fire) everyone who says: ' La ilaha illal-lah,' and has in his heart good equal to the weight of a wheat grain. Then there will come out of Hell (Fire) everyone who says: 'La ilaha illal-lah,' and has in his heart good equal to the weight of an atom (or a smallest ant)."
Allaah Almighty knows best.
