Keeping pace with current trends and technologies, Al-Khawarizmi brings to the world an iPad application that lets you conveniently browse and read through the monumental life of 4 consecutive successors of Sayyiduna Rasoolullah (sallal laahu alaihi wasallam).
Sayyiduna Abu Bakr, Sayyiduna Umar Al Farouq, Sayyiduna 'Uthman Ghani and Sayyiduna Ali (radi Allahu anhumul
ajma'in) were the consecutive successors of Sayyiduna Rasoolullah (sallal laahu alaihi wasallam).
These four Khulafaa are called the "Khulafaa-e-Rashidun" or the "Rightly Guided Caliphs." Together, these
four Khulafaa ruled the Islamic State for about 29 years. They are called "Rightly Guided" because they ruled the people
of that time exactly according to the Holy Quran and the commands of Sayyiduna Rasoolullah (sallal laahu alaihi
Sayyiduna Abdullah ibn Umar (radi Allahu anhuma) has said: "Those who are desirous of following anyone, should follow
the Sahaba who were the best of community, whose hearts were pure, whose wisdom was profound and who did not
believe in the exhibition of outer life. They were a people whom Allah had selected His Nabi (sallal laahu alaihi wasallam)
and who extended His religion to the world. Therefore, try to imitate their ways and manners, for by Allah, they were
rightly guided people."
