Hakim al-Umma Hadhrat Mawlana Ashraf Ali Thanawi (may Allah have mercy on him) said,

‘There are four modes of benefiting from the Divinely pious individuals (ahl-Allah),

Firstly, you gain beneficial knowledge from their speech.

Secondly, you (try to) follow their actions.

Thirdly, they make supplications (dua) for you.

Finally, you get spiritual blessings (barakah) by being in their company.”
