A survey on the holy Quran by thematic induction (al-Istiqrâ al -Ma'nawe) clearly shows Zikro-adder (Dhikrâ al-Dâr) i.e. 'Remembrance of Hereafter' as the root and greatest virtue (trait) of the Quran. The vast extent of its essence in the Quran confirms that this is the supreme leadership concept. It reveals that Allah (swt) endowed this virtue (trait) to Prophet Ibrahim (pbuh) and declared him the leader of mankind and asked Prophet Muhammad (pbuh) to follow Ibrahim (pbuh) as the best model. The introduction of this trait brings about universal vision, wisdom, a keen sense of accountability, motivation, courage, patience, and justice along with all other qualities, values, and virtues (traits) depicted in the Quran. All these contributed to Prophet Muhammad's (pbuh) becoming the most influential leader of all times, who carved out an empire stretching from the border of India to the Atlantic Ocean-the largest empire that world has yet seen.
