Undoubtedly, the heart leans towards those who are kind and gentle. It was said a long time ago: "Make your face happy and your words gentle, and you will be more beloved to the people than those who give them a gift". The one calling to the religion of Islam and dealing with other people has the utmost need to gather the people around him, and cause their hearts to lean towards him so that they will listen to him. Adorning himself with kindness and gentleness helps to achieve that goal with the grace of Allah.

Iqtidaa-ul-‘Ilm al-‘Amal By Al-Khateeb Al-Baghdaadee. This is the second book in the "Classical Knowledge Series", which is a collection of selected scholarly works from the past that deal with the subject of religious knowledge. The first book in this blessed series was “The Book of Knowledge” written by Imaam Abu Khaithamah Zuhayr bin Harb An-Nasaa’ee (Died 234H), may Allah have mercy on him. Since that book served as an introduction to knowledge, its virtues, merits and manners, it seemed proper that the second book be dedicated to the next level of knowledge, which is its result and outcome, and that is righteous deeds. And what better work to present on this subject than the classic and well-known treatise of the distinguished Imaam, Al-Khateeb Al-Baghdaadee, 'Iqtidaa-ul-‘Ilm al-‘Amal' (Knowledge Mandates Action).
