51) Allah has guarenteed to preserve the Qur'an. He says (interp. of the meaning): "Verily, We, it is We Who have sent down the Dhikr (i.e. the Qur'an) and surely, We will guard it (from corruption)." [al-Hijr 15:9]. Everything revealed to the Prophet (peace be upon him) was written down in front of him. The transmission of the Qur'an by memory and writing was mutawaatir, narrated by groups to groups. The Qur'an was compiled by the Sahabah, and Uthman sent copies of the Mus-haf to all the main centers of Islam. There are several ancient manuscripts of the Qur'an in libraries and museums which bear visible testimony to the fact that nothing has been changed in the Book of Allah. Allah says (interpr. of the meaning): "And verily, it is an honorable well fortified respected Book (because it is Allah's Speech, and He has protected it from corruption). Falsehood cannot come to it from before it or behind it , (it is) sent down by thw All Wise, Worthy of all praise (Allah)." [Fussilat 41:41-42]
52) The shaytan has troops whom he sends to keep people from following the religion. They are the ones who prevent people from obeying Allah and push them to commit sins. Allah says (interpr. of the meaning): "And so We have appointed for every Prophet enemies" Shayateen (devils) among mankind and jinn, inspiring one another with adorned speech as a delusion (for by way of deception). If your Lord had so willed, they would not have done it; so leave them alone with their fabrications" [al-An'aam 6:112].
53) The basic principle of religion is that the halal is that which Allah and His Messenger have permitted, and the haram is that which they have forbidden. The religion is that which Allah and His Messenger have prescribed. No one has the right to transgress those limits. Allah says (interp. of the meaning): "And verily, this is My straight path, so follow it, and follow not (other) paths, for they will seperate you away from His path. This He has ordained for you that you may become Al-Muttaqoon (the pious)" [al-An'aam 6:153].
54) Allah offers a great reward if you bear the insults of foolish people with patience in this world. Allah says (interpret. of the meaning): "Beautified is the life of this world for those who disbelieve, and they mock at those who believe. But those who obey Allah's Orders and keep away from what he has forbidden, will be above them on the Day And Allah gives (of His Bounty, Blessings, Favors, and Honors on the Day of Resurrection) to whom He wills without limit." [al-Baqarah 2:212]
55) The believer combines good deeds with fear of punishment: A'ishah asked the Prophet (peace be upon him) about the verse: "And those who give that (their charity) which they give (and also do other good deeds) with their hearts full of fear" [al-Mu'minoon 23:60]
