[13].Surah Ar-Ra'd [The Thunder] : Ayat 33

Ayat 33. Is then He (Allah) Who takes charge (guards, maintains, provides, etc.) of every person and knows all that he has earned (like any other deities who know nothing)? Yet they ascribe partners to Allah. (O Muhammad [SAWW](PBUH) Say: "Name them! Is it that you will inform Him of something He knows not in the earth or is it (just) a show of false words." Nay! To those who disbelieve, their plotting is made fair seeming, and they have been hindered from the Right Path, and whom Allah sends astray, for him, there is no guide.

Hazrat Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah  [SAWW](PBUH) said, "Everyone of my Ummah will enter Jannah except those who refuse". He was asked: "Who will refuse?'' He (PBUH) said, "Whoever obeys me, shall enter Jannah, and whosoever disobeys me, refuses to (enter Jannah)".

[Al-Bukhari Chapter 92, Hadith # 384]. 

Lesson : as mentioned above in Surah Ar-Ra'd Ayat 33. "and they have been hindered from the Right Path, and whom Allah sends astray, for him, there is no guide." The word Ummah here stands for the community which accepted the invitation of the Messenger of Allah  [SAWW](PBUH), that is to say, the people who on his call embraced Islam. Out of this community who follow him faithfully will go to Jannah.
