Allah is the Mudabbir and Khaliq of the Alams. He has determined its systems and runs them accordingly. He operates all this through His Hikmat.
Due to this Qarb Nizaam e Tanhafuz was established. Air was created. We all breathe the Air. We inhale and exhale. This is the breathing system. We can talk and speak and do zikrallah and hamd o sana. We can send durood o salaam on beloved Rasoolallah (s). All this is possible thanks to Allah's system of breathing.
Allah did Tanafukh on Adam (as). Allah did Nafkha on Adam (as). He breathed Rooh in him. Because if the Rooh, Tanafuz ka nizaam came into place. This nizaam draws us towards the Marifat of Allah. This makes us do Allah's zikr and duaa to Him and the desire to please Him. This is how an abd and saalik can get qurb and marifat of Allah.
