Submission to Divine will and trust in Allah is an attribute of believers. On the path of Faqr (Sufism) success depends on continuous effort and trust in Allah.
The saints (Fakirs) are the pious men of Allah. Allah blesses them with spiritual powers and authority but they keep themselves in hiding.
Sultan ul Faqr is the Saint who has accomplished Faqr in its entirety. Faqr is a special spiritual rank and a marvel which has nothing in its comparison.
Intercession is a position and honour of supplication by Allah to His special ones that they will intercede for sinful servants.
