There is so much differences in the Ulama which cause much confusion.

Answer

Hadhrat Shaazli (Rahmatullah alayh), the great Wali of the 11th century said: ―Seek the remedy for your (Imaani) weakness from the Ulama. Listen to them. Choose from them the Muttaqeen (truly pious ones) who are the trustful guides, whose trust is in Allah Ta'ala.‖ They are the Heirs of the Ambiya (Alayhimus salaam).

Follow those Ulama who are not on facebook and the evil internet media. Follow those who are not interfaithers, who do not intermingle with females, who do not indulge in pictography and videography, who do not crawl at the feet of government officials, who do not halaalize carrion, who are not bootlickers of the government and of the wealthy, and who do not barter away the Aakhirat for the jeefah (carrion) of this dunya. You will know them when you see them and when you hear them speak.

There is no conundrum in recognizing them.
