It is necessary for a Muslim, in this day and age, when Islam is overwhelmed by affliction, to play a part in dispelling this disorder. The greatest form of worship in these times is for each and every Muslim to partake in dispelling this disorder. At this time, everyone ought to strive sincerely through their speech, knowledge and every faculty with which they have been endowed, to remove from the world with sincere effort, all the evil and insolence that is currently prevalent.
What good is the comfort and pleasure that one receives in this world? If it is in this world that a person receives their reward then what has been attained? Prefer the reward of the hereafter, which has no limit. Each and every one of you ought to possess a passion for the unity and oneness of God, just as God Himself is passionate for His own unity. Just reflect, where in the world will you find a person who has been wronged more so than our Prophet, peace and blessings of Allah be upon him? There is no filth, abuse or invective that has not been hurled at him. Is this a time when the Muslims should sit silently? At this time, if no one stands up to bear witness to the truth and to silence the ones who speak falsehood, and if one deems it acceptable for disbelievers to go on shamelessly casting aspersions against our Prophet (sa) and continue misguiding the people, then remember that such a Muslim shall undoubtedly be called to account severely. You ought to employ whatever knowledge and experience you have to serve in this cause and save the people from this misfortune…These afflictions began to arise in the thirteenth century, and now the time of their end is near. It is the responsibility of each and everyone of you to strive insofar as possible and show people the light.
