Maseehul-quloob Hazrat Mawlana Maseehullah Khan sahib ra adviced his mureedeen:

“For growth, development and permanence of niyyah (intention that everything being done is solely for Allah SWT’s pleasure via Sunnah method) holdfast to recitation of blessed durood (salawat).

My routine in zikir-e-lisani (remembrance via tongue) is to recite durood all the time.”
