The companions (Radiallaahu Anhum) of Rasulullah (Sallallaahu Alayhi Wa Sallam) are the criterion of the Truth.
It was from the Sahabahs that the world learned what the Deen of Islam was. It is from the Sahabahs that we have been able to establish the true Shariah. It is from the Sahabahs that we obtained the Sunnah of our Nabi (Sallallaahu Alayhi Wa Sallam). The Sahaabah constitute the pivots of Deen of Islam.
They are the upholders and defenders of Deen of Allah.
History cannot show us any other group which has sacrificed so much blood for the glory of Allah's Name than the Sahaabahs - may the pleasure of Allah be with them perpetually!
Hadhrat Shah Waliullah (Rahmatullaahi Alayh) has recorded in his book "Izaala-tul-Khifaa" approximately one hundred verses of the Qur'aan Majeed which put the seal on the sanctity and the elevated position of the Sahabahs.
The Qur'aan Majeed raises the Sahabahs to such a lofty status that to compare them (Sahabahs) with non-Sahabahs would be a grievous error. Said the Holy Prophet (Sallallaahu Alayhi Wa Sallam) "Fear Allah! Fear Allah with regard to my Sahabahs.
Do not make them a target after me. Whosoever loves the Sahabah loves them because of my love. And whosoever dislikes them because he dislikes me. He who harms them has harmed me.
And he who harms me has caused hurt to Allah. And he who causes hurt to Allah Allah will soon grab hold of him."
