Hazrat Moulana Ashraf Ali Thanwi (rahmatullahi ‘alaih) once mentioned:
Nowadays, people expect the condition of the Muslims to improve through merely delivering lectures and bayaans. Although lectures and bayaans are beneficial, merely delivering lectures and bayaans will not be sufficient in bringing about a change unless effort is made towards physically implementing the laws and injunctions of Deen and practising upon them. However, very little attention is paid towards this aspect. People confine their effort to bayaans and its beautiful presentation. (Malfoozaat Hakeemul Ummat 3/145)
