What do you think about DawateIslami, Barelwis and Deobandis. Who are on the right path.?

No one in the right path.

All are called Deviant Groups.

Every group claim they follow quran and sunnah but not right. Each other differ in Aqeedah and Manhaj.

The Prophet of Allah(pbuh) said:

The Jews will split in to 71 Sects.

The Christians will split in to 72 Sects.

My Ummah will split in to 73 Sects.

72 will go to Hell-fire and only one group will go to paradise.

The Companions asked which group is that?

The Prophet(Pbuh) replied: I'm Whereupon and my companions Whereupon.

The only sect that will be safe is Ahlus-Sunnah wal Jama'ah, who adhere to the Sunnah of the Prophet (salallaahu 'alaihi wa sallam), and hold fast to what he and his companions (may Allaah be pleased with them) were holding. It is they about whom the Prophet (salallaahu 'alaihi wa sallam) said: "A group of my Ummah shall remain steadfast, on the truth, victorious, unharmed by those who oppose them, and do not support them, until the death or until the Day of Resurrection."

And Allah Knows Best !
