Muslims need to do all they can — even when they fall short, and do so over and over and over again — to uphold the highest standards of honesty and integrity in everything they do.
For, that is what Islam is all about: Honesty, Truth, Integrity.
And those were the credentials Almighty Allah used to establish Muhammad, Sallallahu Alaihi wa Sallam, in this world as the future Rasul, his very last Rasul — Khaatamul Anbiyaa, Sallallahu Alaihi wa Sallam — for this world, for all times to come.
Almighty Allah got the whole world to recognize a youthful Muhammad, Sallallahu Alaihi wa Sallam, as As-Saadiq and Al-Ameen: the Truthful One and the Trustworthy One, way before he made him a Rasul.
And Allah did that in the Society of Arabia in which lying, cheating, deceiving were pretty much as common as they are in our own societies today.
And the Poet of Islam Iqbal asks Muslims to Relearn the Lessons of Honesty and Truthfulness, and Justice, because those will be the credentials and qualifications that the world will seek to see if it will accept you as Leaders, one more time in this world, and in the history of human civilization.
Sabaq Phir Padh Sadaaqat Kaa,
Liyaa Jaa-ey Ga Tujh Sey Kaam
Duniya Ki Imaamat Kaa.
