Firstly: To strive in learning guidance and the religion of truth, without which there will be no success. Indeed, there can be no true happiness, nor any delight in this world and in the Hereafter, except through it.
Secondly: Striving to act upon what has been learnt, since knowledge without action will not benefit, rather it will cause harm.
Thirdly: Striving to invite others towards it and to teach those who do not know, otherwise he may be considered from those who hide what Allaah has revealed of guidance and clear explanation. Such knowledge will neither benefit, nor save a person from the punishment of Allaah.
Fourthly: Striving to be patient and persevering against those who oppose this da’wah (call) to Allaah and those who seek to cause harm – patiently bearing all these hardships for the sake of Allaah.
When these four stages are completed then such a person is considered to be amongst the Rabbaaniyyoon. The Salaf were agreed that a Scholar does not deserve the title of Rabbaanee until he recognises and knows the truth, acts upon it, and teaches it to others. So whosoever has knowledge, acts upon it, and teaches this knowledge to others, is considered from the Rabbaaniyyoon.“
