The obstacles:

The obstacles:

The obligation is to warn against the obstacles, which delay the person on his way to Allah and obtaining His pleasure, and these are three: 1. The shirk with Allah, 2. Bid'ah in the religion of Allah (Innovations in Islam), 3. The sins in all its kinds.

As for the obstacle of Shirk, the safety from it is obtained with sincerity of tawheed to Allah and singling Him out in the worship.

As for the obstacle of Innovation, the safety from it is obtained by sticking to the sunnah and following the guidance of the Prophet sallallahu alayhe wa sallam.

As for the obstacle of sin, the safety from it is obtained by staying away from it and making sincere repentance when falls into something of it.
