Securing Oneself Against Everlasting Disasters

Hadrat Yusuf Nabhani says in his booklet Khulasa-t-ul-kalam:

Adapting oneself to a certain religion is for attaining eternal happiness and securing oneself against everlasting disasters. It is not for boasting about a religion which one has inherited from one's parents. And each Prophet is a human being who possesses the qualifications of prophethood and conveys the injunctions of Allahu ta'ala to His born slaves. One has to adapt oneself to a Prophet who has these qualifications and enter his religion. People who worship icons and idols called Wasani (Veseni) and godless people called Dehri, [also freemasons and communists] are like beasts. Also, the Nazarene (Christian) and Judaic religions have become obsolete for the following reasons:

1- In the Islamic religion, Allahu ta'ala has attributes of perfection. He does not have attributes of deficiency. The worships are easy to perform. Social relations are based on justice. Worships and social relations taught in the other religions, however, have changed in the course of time, so that they are no longer reasonable or practicable.
2- A comparative study of the lives of Muhammad, Isa (Jesus) and Musa (Moses) 'alaihimus-salam' will show that Muhammad 'alaihis-salam' is of the highest lineage, the noblest, the bravest, the most beneficent, the most knowledgeable, the wisest, the most superior, and the most sagacious in knowledge pertaining to this world and the next. On the other hand, he was ummi (illiterate). In other words, he had never read books nor learned anything from anybody.
3- The mu'jizas (miracles) worked through Muhammad 'alaihis-salam' were much more numerous than the total of those wrought through the others. The mu'jizas of the others are past and over. A number of Muhammad's 'alaihis-salam' mu'jizas, on the other hand, especially the mu'jiza of Qur'an al-karim, have been continuing and will last till the end of the world. And the keramats of his Ummat (Muslims), especially those wrought through the Awliya [1], have been occurring continually and everywhere.
4- Among the reports communicating these three religions to us, those which are conveyed through Qur'an al-karim and hadith-i-sharifs [2] are more numerous and more dependable. All of them have been committed to books and spread throughout the world.

They did not let false statements fabricated by liars [and Jews] in the name of hadiths enter their books. They were very stringent, extremely sensitive in this respect. None of the other religions spread in such a healthy way.

[1] awliya: (pl. of Wali) a person loved by Allahu ta'ala.
[2] hadith (sharif): i) a saying of the Prophet ('alaihi 's-salam).; al-Hadith ash-sharif: all the hadiths as a whole; ii) 'ilm al-hadith; iii) Books of the hadith ash-sharif. iv) Al-hadith al-qudsi, as-sahih, al-hasan: kinds of hadiths (for which, see Endless Bliss, II).
