Mawlana Shams al-Haq Afghani (may Allah shower his mercy upon him) related:
Our teacher Shaykh al-Islam Mawlana Muhammad Anwar Shah Kashmiri would say: ‘‘Mawlana ‘Abd al-Hayy Lucknowi is dependable in his opinions. However, the reverence for him in my heart is due to his piety (taqwa). One of his students informed me, ‘‘I remained in Mawlana Lucknowi’s company for seven years. In all that time – despite having many opponents – I did not hear him utter a word of ghibah.’’ (Our revered teacher, [‘Allamah Anwar Shah] Kashmiri would say), ‘‘this is a quality which is rare among scholars, let alone the masses.’’
