This short treatise, "LIVE LIKE BROTHERS - DEAL LIKE STRANGERS" is a translation of an article by Hazrath Mufti Muhammad Taqi Usmani Saheb (mudda Zilluhu). The original article titled "Mua'malaat Ki Safai Aur Tanazu 'aat" was published in the July-94 issue of the monthly urdu magazine Al-Balaagh.

Hazrath Mufti Muhammad Taqi Saheb (mudda zilluhu), in his capacity as a judge of the Shariah court, has immense experience in these matters. In the light of this experience he has vividly described the common problems that repeatedly occur in our dealings - and has given practical solutions to these problems.
