Hazrat Sultan Mahmood al Ghaznawi Rahmatullah alaih, used to recite as a wazeefah [ma'moolaat] with pure intentions and a lot of love this Darood one lakh times. Because of reading this long Darood one hundred thousand times, the whole day would go by and he wouldn't have much time for the administration of government. One night he saw Sayyidina Rasuli Akram Sall Allahu alaihi wa Aalihi wa Sallim, who informed Hazrat Sultan Mahmood Rahmatullah alaih that the Ummat was is need of his work and the administration of government is dependent on Hazrat Sultan Mahmood al Ghaznawi.
