A complete human is one who has knowledge, purity of deed, one whose physical appearance is correct (as per Sunnah), heart (spititual) is cleansed, one whose intentions are pure and intentions do not become pure until one does not have the fear of standing in front of Allah (in the day of judgment)
– Shaykh Sayyid Muhammad Talha Qasmi Naqshbandi (d.b)
