Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) once mentioned to some of his close associates:
Hazrat Umar (radhiyallahu ‘anhu) would say to Hazrat Abu Ubaidah (radhiyallahu ‘anhu) and Hazrat Mu’aaz (radhiyallahu ‘anhu), “Though I am the Khalifah, I am not independent of you. I am still in need of your advising me and guiding me if I err.”
Hazrat Moulana Ilyaas (rahmatullahi ‘alaih) thereafter mentioned, “Similarly, I am also requesting you to continue advising me and correcting me wherever you see me err.” (Malfoozaat Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) pg.114)
