In the book, The Call of the Quran, Maulana Wahiduddin Khan explains that it is the duty of every Muslim man, woman and child to study the Quran and follow it. He further explains that it is also the responsibility of the Muslims to convey the message of the Quran to other nations. Therefore, the Quran urges the Muslims time and again to carry out this task: ‘strive with the utmost strenuousness by means of this (The Quran).’ (The Quran 25: 52) It is a fact that the Muslims' unity is their greatest strength. The best means of achieving this unity is the call towards God. In his last sermon, Prophet Muhammad urged his followers to convey the message of the Quran ‘even if only a single verse.’ Therefore, Muslims must perform this task in all sincerity till the Last Day; therein lies our entire success, both in this world and in the world to come.
