Imam al Hassan (peace be upon him) said:

O people, he who advises for God’s sake and betakes His sayings as guidance will surely be led to the most upright way and God will grant him success to the right guidance and will direct him to the best. The disciple of God is certainly secured and preserved while His enemy is surely fearful and disappointed. Be cautious of God by very much mention of Him, fear Him by means of God-fearing, and approach to Him through obedience to Him, for He is surely near and replying.

God the Blessed the Elevated says:

If any of My servants ask you about Me, tell them that the Lord says, “I am near; I accept the prayers of those who pray.” Let My servants answer My call and believe in Me so that perhaps they may know the right direction.

Answer God and believe in Him because it is improper for anyone who acknowledges God’s greatness to behave arrogantly. The sublimity of those who acknowledge God’s greatness is certainly their modesty, the dignity of those who acknowledge God’s majesty is their submission to Him, and the safety of those who acknowledge God’s power is to acquiesce to Him and to avoid denying after acknowledgement and deviating after guidance.

You should know convectively that you will not recognize God-fearing before you realize the character of guidance, you will not hold on the bond of the Book before you know those who deserted it, and you will not recite the Book so properly before you know those who distorted it. After you know all these, you will know heresies and overacting, will see forgery against God and distortion, and will know how the declining ones fell. Let not the ignorant engage you in their ignorance. Seek these from their proper people, for they are surely the light by which enlightenment is sought and the leaders whose examples should be followed. By them, knowledge survives and ignorance fades away. Their clemency refers to their ignorance, their utterance of wisdom refers to their silence, and their appearance refers to their hidden. They neither oppose the right nor do they disagree about it. Different traditions existed before them and God’s decision passed before them. This is surely a reminder for those who mention. When you hear it, you should understand it heedfully, not just for relation. The relaters are certainly numerous while the heedful are few. God is the One Whose help is sought.
