In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
NB: Although disobedience and sinning brings about calamity and humiliation, however there will always be people of guidance and steadfastness. Shaikh Saaleh Al-Fawzaan (may Allaah preserve him) said: [A person] should not lose hope when trials and evil increases. Indeed, he has to remain upon tranquillity and should make others tranquil when trials occur, and he should say: ‘’All Praise is due to Allaah, we are upon guidance and a clear Religion. Solace is close by and evil will cease to exist by the permission of Allaah’’ This is what is incumbent upon THE PEOPLE OF GOOD AND THE SCHOLARS–that they have tranquillity and make the people tranquil; because this (EVIL) is something that will cease to exist by the permission of Allaah and solace will come after it.
It is not permissible for a person to say: ‘’the people are destroyed.’’ This is not permissible; rather (a person) should make the people tranquil, firm upon goodness, whilst expecting assistance, for indeed the good end is for the people of piety. Therefore, no matter how great the evil and trial is, it will cease to exist. He (sallal-laahu-alayhi-wasallam) said: ‘’A group of my followers will remain manifest upon the truth. They will neither be harmed by those who forsake them nor by those who oppose them till Allaah’s command arrives.” [i.e. the day of judgement] [Bukhari and Muslim]
Therefore, Islaam will not cease to continue and all praise be to Allaah. The Religion and the Qur’aan will not cease to exist until that appointed time which the prophet (sallal-laahu-alayhi-wasallam) has informed us of – that at the end of time the Qur’aan will be taken away from the hearts of men and from the masaahif (i.e. the copies of the Qur’aan); but this will be at the time of the destruction of the world. (However) good will continue to exist whilst the Qur’an, the Sunnah and the Qiblah are present, even though there is one who is led away from it and becomes misguided; and even though there is one who deviates from it and becomes deviated, as the saying goes: ‘’Fitnah has its victims’’. It takes away the one who goes with it; but the people of Eemaan will remain even if they are small in number. Even if there is one who goes along with the Fitnah, and the one who goes astray and the one who comes along with it, (still) the truth and its people will remain and all praise be to Allaah. The truth is present, as Allaah (The Exalted and Most High) said: [إِنَّا نَحْنُ نَزَّلْنَا الذِّكْرَ وَإِنَّا لَهُ لَحَافِظُونَ – Verily We: It is We Who have sent down the Dhikr (i.e. the Qur’an) and surely, We will guard it (from corruption) 15:9]
A person should not lose hope nor should he despair. He should not make the people lose hope of a return to goodness. He should not make the people lose hope regarding (the fact) that truth will prevail and falsehood will be repelled because Allaah (Glorified and Exalted Be He) has made that promise and He does not fail to fulfill His promise. Imaam Ibnul Qayyim (rahimahullaah) said: ‘’The Religion is aided when put to the test; therefore do not be amazed for this is the way of Ar-Rahmaan (The Most Merciful). http://www.salaficentre.com/2013/09/updated-the-people-used-to-ask-about-the-good-hudhaifah-radiyallaahu-anhu/
