Hadhrat Mufti Mahmud Hasan Gangohi (ra) once narrated:
Once , Hadhrat Maulana Sayyad Husayn Ahmad Madni (ra) said to his students, ” You people receive two pieces of roti (chapatti) from the [madrassah] kitchen and you eat both of them. You are not able to suffice on one a half pieces and give half a piece to a poor person. Similarly, you sleep on mattresses and rest your head on pillows. As long as I was a Talib al-Ilm (student of sacred knowledge), I never slept on a mattress and never rested my head against a pillow. Instead, I would place a brick under my head and sleep.
